Sanitizers target modificators
Depends on bool flag fix: https://github.com/rust-lang/rust/pull/138483.
Some sanitizers need to be target modifiers, and some do not. For now, we should mark all sanitizers as target modifiers except for these: AddressSanitizer, LeakSanitizer
For kCFI, the helper flag -Zsanitizer-cfi-normalize-integers should also be a target modifier.
Many test errors was with sanizer flags inconsistent with std deps. Tests are fixed with `-C unsafe-allow-abi-mismatch`.
This was done in #145740 and #145947. It is causing problems for people
using r-a on anything that uses the rustc-dev rustup package, e.g. Miri,
clippy.
This repository has lots of submodules and subtrees and various
different projects are carved out of pieces of it. It seems like
`[workspace.dependencies]` will just be more trouble than it's worth.

Review everything that uses `MacroKind`, and switch anything that could
refer to more than one kind to use `MacroKinds`.
Add a new `SyntaxExtensionKind::MacroRules` for `macro_rules!` macros,
using the concrete `MacroRulesMacroExpander` type, and have it track
which kinds it can handle. Eliminate the separate optional `attr_ext`,
now that a `SyntaxExtension` can handle multiple macro kinds.
This also avoids the need to downcast when calling methods on
`MacroRulesMacroExpander`, such as `get_unused_rule`.
Integrate macro kind checking into name resolution's
`sub_namespace_match`, so that we only find a macro if it's the right
type, and eliminate the special-case hack for attributes.
When trying to construct a struct that has a public field of a private type, suggest using `..` if that field has a default value.
```

LL | let _ = S { field: (), field1: m::Priv1 {} };

note: the struct `Priv1` is defined here
--> $DIR/non-exhaustive-ctor.rs:14:4
|
LL | struct Priv1 {}
| ^^^^^^^^^^^^
help: the field `field1` you're trying to set has a default value, you can use `..` to use it
|
LL | let _ = S { field: (), .. };

rustc_metadata: remove unused private trait impls
These are impls for non-reachable traits that don't appear to be used. Please let me know if there is value in keeping some of them for now.
cc `@cjgillot`
The metadata symbol must not be encoded in the crate metadata, and must
be exported from proc-macros. Handling the export of the metadata symbol
in exported_symbols handles both things at once without requiring manual
fixups elsewhere.
Tracks association between `self.sess.opts.externs` (aliases in `--extern alias=rlib`) and resolved `CrateNum`
Intended to allow Rustdoc match the aliases in `--extern-html-root-url`
Force-injected extern crates aren't included, since they're meant for the linker only
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`?
