Tracking issue: #116909

The fix for llvm/llvm-project#50374 made it into LLVM 21, so these examples work now.

https://rust.godbolt.org/z/qTzMG4ffc

But the doc tests only ran on x86_64 linux before, so removing the cfg makes them suddenly run on many more targets, some of which might still fail. We may need to wait until we're on LLVM 22 if other issues do pop up.

LLVM issue 50374 was closed a while ago, and the fix made it into LLVM 21, so these examples no longer crash
