…c::exit` or returns from `main`.
1. Miri's exit is thread-safe 2. Miri doesn't (yet) support `libc::gettid`, used in the implementation of the mitigation on Linux.
… generic function, and wrap it in `catch_unwind`
Provided methods currently don't get type erasure performed on them because they are not in an `impl` block. If we are instantiating a method that is an associated item, but *not* in an impl block, treat it as a provided method instead.

…es, r=estebank Ignore allocation bytes in some mir-opt tests This adds `rustc -Zdump-mir-exclude-alloc-bytes` to skip writing allocation bytes in MIR dumps, and applies it to tests that were failing on s390x due to its big-endian byte order. Fixes rust-lang#126261
Guard against calling `libc::exit` multiple times on Linux. Mitigates (but does not fix) rust-lang#126600 by ensuring only one thread which calls Rust `exit` actually calls `libc::exit`, and all other callers of Rust `exit` block.
…estebank add lint for inline asm labels that look like binary fixes rust-lang#94426 Due to a bug/feature in LLVM, labels composed of only the digits `0` and `1` can sometimes be confused with binary literals, even if a binary literal would not be valid in that position. This PR adds detection for such labels and also as a drive-by change, adds a note to cases such as `asm!(include_str!("file"))` that the label that it found came from an expansion of a macro, it wasn't found in the source code. I expect this PR to upset some people that were using labels `0:` or `1:` without issue because they never hit the case where LLVM got it wrong, but adding a heuristic to the lint to prevent this is not feasible - it would involve writing a whole assembly parser for every target that we have assembly support for.

CFI: Support provided methods on traits Provided methods currently don't get type erasure performed on them because they are not in an `impl` block. If we are instantiating a method that is an associated item, but *not* in an impl block, treat it as a provided method instead.
…rt-ice, r=estebank Fix import suggestion ice Fixes rust-lang#127302 rust-lang#127302 only crash in edition 2015 rust-lang#120074 can only reproduced in edition 2021 so I added revisions in test file.
…rn_blocks, r=oli-obk Fire unsafe_code lint on unsafe extern blocks Fixes rust-lang#126738
…=lcnr Remove `fully_normalize` Yeet this function and replace it w/ some `ObligationCtxt` instead. It wasn't called very often anyways. r? lcnr
…rustdoc, r=fmease Implement `precise_capturing` support for rustdoc Implements rustdoc (+json) support for local (i.e. non-cross-crate-inlined) RPITs with `use<...>` precise capturing syntax. Tests kinda suck. They're really hard to write 😰 r? `@fmease` or re-roll if you're too busy! also cc `@aDotInTheVoid` for the json side Tracking: * rust-lang#127228 (comment) (not fully fixed for cross-crate-inlined opaques) * rust-lang#123432
