This makes `const` contexts use the `const`-stability version
information instead of the regular stability one, as `const`-stability
may happen much later than stability in non-`const` contexts.
~~It includes the content of PR rust-lang/rust-clippy#15296 as its first
commit. I separated them because this one is more complex, and
rust-lang/rust-clippy#15296 may be merged more rapidly.~~
changelog: [`incompatible_msrv`]: check the right MSRV when in a `const`
context
r? Jarcho @rustbot label +C-bug +I-false-negative
The test relies on LLVM not merging all the globals into one and would
currently otherwise fail on powerpc64le.

From `#[align]` -> `#[rustc_align]`. Attributes starting with `rustc`
are always perma-unstable and feature-gated by `feature(rustc_attrs)`.
See regression RUST-143834.
For the underlying problem where even introducing new feature-gated
unstable built-in attributes can break user code such as
```rs
macro_rules! align {
() => {
/* .. */
};
}
pub(crate) use align; // `use` here becomes ambiguous
```
refer to RUST-134963.
Since the `#[align]` attribute is still feature-gated by
`feature(fn_align)`, we can rename it as a mitigation. Note that
`#[rustc_align]` will obviously mean that current unstable user code
using `feature(fn_aling)` will need additionally `feature(rustc_attrs)`,
but this is a short-term mitigation to buy time, and is expected to be
changed to a better name with less collision potential.

where mitigation options were considered.
This alias was added in 9897bfb8a ("Fix memset arguments for MSP430
target"), which predates `core::ffi`. Now that it exists we can just use
`core::ffi::c_int`.
Generalize `unsize` and `unsize_into` destinations
Just something that I noticed during other work. We do this for most such functions, so let's do it here, too.

Refactor `CrateLoader` into the `CStore`
Removes the `CrateLoader` and moves the code to `CStore`. Now, if you want to use the `CrateLoader`, you can just use `CStore`.
Should we rename `creader.rs` to `cstore.rs`?

Fix encoding of link_section and no_mangle cross crate
Fixes https://github.com/rust-lang/rust/issues/144004
``@bjorn3`` suggested using the `codegen_fn_attrs` query but given that these attributes are not that common it's probably fine to just always encode them. I can also go for that solution if it is preferred but that would require more changes.

opt-dist: make llvm builds optional
adds command line option for disabling llvm builds. it's useful in case of user having their own optimized LLVM, so they won't waste time for (at least) 3 LLVM builds. in this case PGO optimized rustc will be already built in Stage 1, so rust-lang/rust#143898 should be addressed for this change

I want to improve memory dumps in general. Not sure yet how to do so best within rust diagnostics, but in a perfect world I could generate a dummy in-memory file (that contains the rendered memory dump) that we then can then provide regular rustc `Span`s to. So we'd basically report normal diagnostics for them with squiggly lines and everything.
This test depends on the target-specific behavior of crt-static for musl
targets. However, running the testsuite on a musl host requires
setting `crt-static` to `false`, as it wouldn't otherwise be possible to
build rustc. This in turn will enable `-Ctarget-feature=-crt-static` for
all tests, mismatching the expected `+crt-static` for the musl target
tested in this testcase.
Since this test specifically tests the default value of `crt-static` for
the musl target, ignoring it entirely makes more sense than manually
setting `-Ctarget-feature=+crt-static` here, but both would be valid
approaches.

The current behaviour introduced by commit
a50a3b8e318594c41783294e440d864763e412ef would discard any
target features specified after crt-static (the only member of
RUSTC_SPECIFIC_FEATURES). This is because it returned instead of
continuing processing the next flag.
