Rollup merge of #111369 - Nassiel:master, r=oli-obk 
Added custom risc32-imac for esp-espidf target

ESP32-C6 and the upcoming ESP32-P4 are the first Espressif chips that support the "A" (atomic) extension of the RISCV specification.
As such, they do not work with the existing `riscv32imc-esp-espidf` target and instead need a new one (in this PR) called `riscv32imac-esp-espidf`.

Rollup merge of #111058 - fortanix:raoul/fix_lvi_mitigations, r=cuviper 
Correct fortanix LVI test print function

A recent change resulted in a different machine code for the `print` function. This caused the LVI test for this function to fail. This PR:

- Fixes the test for the `print` function
- Simplified the test a bit so future modifications are more unlikely

fd9bf59436 Auto merge of #111999 - scottmcm:codegen-less-memcpy, r=compiler-errors 
Use `load`+`store` instead of `memcpy` for small integer arrays

I was inspired by #98892 to see whether, rather than making `mem::swap` do something smart in the library, we could update MIR assignments like `*_1 = *_2` to do something smarter than `memcpy` for sufficiently-small types that doing it inline is going to be better than a `memcpy` call in assembly anyway.  After all, special code may help `mem::swap`, but if the "obvious" MIR can just result in the correct thing that helps everything -- other code like `mem::replace`, people doing it manually, and just passing around by value in general -- as well as makes MIR inlining happier since it doesn't need to deal with all the complicated library code if it just sees a couple assignments.

LLVM will turn the short, known-length `memcpy`s into direct instructions in the backend, but that's too late for it to be able to remove `alloca`s.  In general, replacing `memcpy`s with typed instructions is hard in the middle-end -- even for `memcpy.inline` where it knows it won't be a function call -- is hard [due to poison propagation issues](https://rust-lang.zulipchat.com/#narrow/stream/187780-t-compiler.2Fwg-llvm/topic/memcpy.20vs.20load-store.20for.20MIR.20assignments/near/360376712).  So because we know more about the type invariants -- these are typed copies -- rustc can emit something more specific, allowing LLVM to `mem2reg` away the `alloca`s in some situations.

#52051 previously did something like this in the library for `mem::swap`, but it ended up regressing during enabling mir inlining (cbbf06b0cd), so this has been suboptimal on stable for ≈5 releases now.

The code in this PR is narrowly targeted at just integer arrays in LLVM, but works via a new method on the [`LayoutTypeMethods`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_codegen_ssa/traits/trait.LayoutTypeMethods.html) trait, so specific backends based on cg_ssa can enable this for more situations over time, as we find them.  I don't want to try to bite off too much in this PR, though.  (Transparent newtypes and simple things like the 3×usize `String` would be obvious candidates for a follow-up.)

Codegen demonstrations: <https://llvm.godbolt.org/z/fK8hT9aqv>

Before:
```llvm
define void `@swap_rgb48_old(ptr` noalias nocapture noundef align 2 dereferenceable(6) %x, ptr noalias nocapture noundef align 2 dereferenceable(6) %y) unnamed_addr #1 {
  %a.i = alloca [3 x i16], align 2
  call void `@llvm.lifetime.start.p0(i64` 6, ptr nonnull %a.i)
  call void `@llvm.memcpy.p0.p0.i64(ptr` noundef nonnull align 2 dereferenceable(6) %a.i, ptr noundef nonnull align 2 dereferenceable(6) %x, i64 6, i1 false)
  tail call void `@llvm.memcpy.p0.p0.i64(ptr` noundef nonnull align 2 dereferenceable(6) %x, ptr noundef nonnull align 2 dereferenceable(6) %y, i64 6, i1 false)
  call void `@llvm.memcpy.p0.p0.i64(ptr` noundef nonnull align 2 dereferenceable(6) %y, ptr noundef nonnull align 2 dereferenceable(6) %a.i, i64 6, i1 false)
  call void `@llvm.lifetime.end.p0(i64` 6, ptr nonnull %a.i)
  ret void
}
```
Note it going to stack:
```nasm
swap_rgb48_old:                         # `@swap_rgb48_old`
        movzx   eax, word ptr [rdi + 4]
        mov     word ptr [rsp - 4], ax
        mov     eax, dword ptr [rdi]
        mov     dword ptr [rsp - 8], eax
        movzx   eax, word ptr [rsi + 4]
        mov     word ptr [rdi + 4], ax
        mov     eax, dword ptr [rsi]
        mov     dword ptr [rdi], eax
        movzx   eax, word ptr [rsp - 4]
        mov     word ptr [rsi + 4], ax
        mov     eax, dword ptr [rsp - 8]
        mov     dword ptr [rsi], eax
        ret
```

Now:
```llvm
define void `@swap_rgb48(ptr` noalias nocapture noundef align 2 dereferenceable(6) %x, ptr noalias nocapture noundef align 2 dereferenceable(6) %y) unnamed_addr #0 {
start:
  %0 = load <3 x i16>, ptr %x, align 2
  %1 = load <3 x i16>, ptr %y, align 2
  store <3 x i16> %1, ptr %x, align 2
  store <3 x i16> %0, ptr %y, align 2
  ret void
}
```
still lowers to `dword`+`word` operations, but has no stack traffic:
```nasm
swap_rgb48:                             # `@swap_rgb48`
        mov     eax, dword ptr [rdi]
        movzx   ecx, word ptr [rdi + 4]
        movzx   edx, word ptr [rsi + 4]
        mov     r8d, dword ptr [rsi]
        mov     dword ptr [rdi], r8d
        mov     word ptr [rdi + 4], dx
        mov     word ptr [rsi + 4], cx
        mov     dword ptr [rsi], eax
        ret
```

And as a demonstration that this isn't just `mem::swap`, a `mem::replace` on a small array (since replace doesn't use swap since #83022), which used to be `memcpy`s in LLVM changes in IR
```llvm
define void `@replace_short_array(ptr` noalias nocapture noundef sret([3 x i32]) dereferenceable(12) %0, ptr noalias noundef align 4 dereferenceable(12) %r, ptr noalias nocapture noundef readonly dereferenceable(12) %v) unnamed_addr #0 {
start:
  %1 = load <3 x i32>, ptr %r, align 4
  store <3 x i32> %1, ptr %0, align 4
  %2 = load <3 x i32>, ptr %v, align 4
  store <3 x i32> %2, ptr %r, align 4
  ret void
}
```
but that lowers to reasonable `dword`+`qword` instructions still
```nasm
replace_short_array:                    # `@replace_short_array`
        mov     rax, rdi
        mov     rcx, qword ptr [rsi]
        mov     edi, dword ptr [rsi + 8]
        mov     dword ptr [rax + 8], edi
        mov     qword ptr [rax], rcx
        mov     rcx, qword ptr [rdx]
        mov     edx, dword ptr [rdx + 8]
        mov     dword ptr [rsi + 8], edx
        mov     qword ptr [rsi], rcx
        ret
```

Rollup merge of #112318 - oli-obk:assoc_ty_sized_bound_for_object_safety, r=compiler-errors 
Merge method, type and const object safety checks

cc `@spastorino` and `@compiler-errors` on the first commit. I believe it to be correct, as the field is only `Some` for assoc types, so just checking the field without checking the assoc kind to be `Type` is fine.

The second commit avoids going through all associated items thrice and just goes over all of them once, running the object safety checks per assoc item kind.

Rollup merge of #112303 - Nilstrieb:as-deref, r=compiler-errors 
Normalize in infcx instead of globally for `Option::as_deref` suggestion

fixes #112293

The projection may contain inference variables. These inference variables are local to the local inference context. Using `tcx.normalize_erasing_regions` doesn't work here because this method is global and does not have access to the inference context. It's therefore unable to deal with the inference variables. We normalize in the local inference context instead, which knowns about the inference variables.

The test looks a little different than the issue example, I made it more minimal and verified that it still ICEs on nightly.

Also contains a drive-by fix to properly compare the types.

Rollup merge of #112196 - compiler-errors:new-solver-resolv, r=lcnr 
Resolve vars in result from `scrape_region_constraints`

Since we perform `type_op::Normalize` in the local infcx when the new solver is enabled, vars aren't necessarily resolved, which triggers this ICE:

f85ab544df/compiler/rustc_infer/src/infer/nll_relate/mod.rs (L481)

There are more tests that go from ICE -> pass due to this change, but I just added revisions to a few for CI.

I want to investigate why `-C line-tables-only` is still ~tripling the size of the binary (update: done https://github.com/rust-lang/rust/pull/110221#issuecomment-1507563024), but this seems like a good improvement in the meantime.

I've tested that both valgrind and perf can read the debuginfo:

To test this, you can run `x build --stage 0 cargo`, set `build.cargo = "build/host/stage0-tools-bin/cargo"`, and then `x build --stage 2 std`. You should be able to compare the rustc_driver.so outputs to each other:
```
; ls -lh build/host/stage{0,1,2}/lib/librustc_driver*.so
-rw-r--r-- 1 jyn jyn 130M Mar  6 15:24 build/host/stage0/lib/librustc_driver-f265b505c593f632.so
-rwxrwxr-x 3 jyn jyn 216M Apr 11 00:51 build/host/stage1/lib/librustc_driver-3aa1aa8c8214a2de.so
-rwxrwxr-x 4 jyn jyn 186M Apr 11 00:54 build/host/stage2/lib/librustc_driver-02d96489c468b21e.so
```

The difference between stage1 and stage2 is `debuginfo=1` vs `debuginfo=line-tables-only`. Both stages have `-gz` (compressed debuginfo) enabled.

This depends on https://github.com/rust-lang/cargo/pull/11958 (and the exact commit of the cargo submodule will need to change before merging).

Helps with https://github.com/rust-lang/rust/pull/104968.

c6a3fe051a Auto merge of #14978 - HKalbasi:lifetime-display, r=HKalbasi 
Emit `'_` for lifetime generics in `HirDisplay`

This makes the generated code not linted by `rust_2018_idioms` lint. But that is an allow by default lint, so should we do this? Maybe we should only do this for `DisplayTarget::SourceCode`?

5eeeed1aa1 Greatly decrease the size of rustc_driver.so when debuginfo is enabled 
- Only add -gz if it's supported
- Don't include extra unnecessary debuginfo when only debuginfo-level=1 is set
- Compress debuginfo sections to reduce the size of debuginfo on disk.

before: 650 MB
line tables only: 335 MB
compressed only: 216 MB
compressed and line tables: 186 MB
no debuginfo at all: 130 MB

I want to investigate why `-C line-tables-only` is still ~tripling the
size of the binary, but this seems like a good improvement in the
meantime.

I've tested that both valgrind and perf can read the debuginfo:

Show note for type ascription on a local binding interpreted as a constant pattern and not a new variable

Given the code

```rust
pub fn main() {
    const y: i32 = 4;
    let y: i32 = 3;
}
```

`y` in the let binding is actually interpreted as a constant pattern and is not a new variable, causing confusing diagnostics about refutable patterns in local binding.

This PR extends the note for type ascription of a constant pattern to `AscribeUserType` patterns which have `Constant` subpatterns.

Fixes #112269.

Fix type-inference regression in #112225

The type inference of argument-position closures and async blocks regressed in 1.70 as the evaluation order of async blocks changed, as they are not implicitly wrapped in an identity-function anymore.

Fixes #112225 by making sure the evaluation order stays the same as it used to.

r? `@compiler-errors`

As this was a stable-to-stable regression, it might be worth to consider backporting. Although the workaround for this is trivial as well: Just wrap the async block in another block.
