…RalfJung s390x: Fix a regression related to backchain feature In rust-lang#127506, we introduced a new IBM Z-specific target feature, `backchain`. This particular `target-feature` was available as a function-level attribute in LLVM 17 and below, so some hacks were used to avoid blowing up LLVM when querying the supported LLVM features. This led to an unfortunate regression where `cfg!(target-feature = "backchain")` will always return true. This pull request aims to fix this issue, and a test has been introduced to ensure it will never happen again. Fixes rust-lang#129927. r? `@RalfJung`

I can't reproduce it on my local device (Linux). Unfortunately, I don't own an Apple device to test the issue |
mmh, lets see if this can land on its own then @bors r=RalfJung rollup=iffy |
Sounds unlikely that this PR would lead to an LLVM crash... I guess we'll see. |
