bors 7660aed73d Auto merge of #132173 - veluca93:abi_checks, r=RalfJung,compiler-errors 
Emit warning when calling/declaring functions with unavailable vectors.

On some architectures, vector types may have a different ABI depending on whether the relevant target features are enabled. (The ABI when the feature is disabled is often not specified, but LLVM implements some de-facto ABI.)

As discussed in rust-lang/lang-team#235, this turns out to very easily lead to unsound code.

This commit makes it a post-monomorphization future-incompat warning to declare or call functions using those vector types in a context in which the corresponding target features are disabled, if using an ABI for which the difference is relevant. This ensures that these functions are always called with a consistent ABI.

See the [nomination comment](https://github.com/rust-lang/rust/pull/127731#issuecomment-2288558187) for more discussion.

Part of #116558

README.md

This is serves as a collection of crashes so that accidental ICE fixes are tracked. This was formally done at https://github.com/rust-lang/glacier but doing it inside the rustc testsuite is more convenient.

It is imperative that a test in the suite causes an internal compiler error/panic or makes rustc crash in some other way. A test will "pass" if rustc exits with something other than 1 or 0.

When adding crashes from https://github.com/rust-lang/rust/issues, the issue number should be noted in the file name (12345.rs should suffice) and also inside the file via //@ known-bug #4321 if possible.

If you happen to fix one of the crashes, please move it to a fitting subdirectory in tests/ui and give it a meaningful name. Also please add a doc comment at the top of the file explaining why this test exists. :) Adding Fixes #NNNNN Fixes #MMMMM to the description of your pull request will ensure the corresponding tickets will be closed automatically upon merge. The ticket ids can be found in the file name or the known-bug annotation inside the testfile.

Please do not re-report any crashes that you find here!
