identifier z crashes LLVM used in Emscripten

[bottle2]

Description / Steps to reproduce the issue

hi, I reported this upstream: emscripten-core/emscripten#23383

I made the mistake of also reporting too upstream too early: llvm/llvm-project#122793

steps to reproduce:

1. create a file test.c solely with this content: int z; or int z(int);
2. compile object with emcc -c test.c

affects version 3.1.74, but not 3.1.72.

I wanted to use my PKGBUILD and Arch Linux knowledge from 5 years ago to git bisect the culprit commit, but... I'm tired and I my laptop is crappy and I'm afraid of compile times. would you please bump the LLVM version to a version where this crash doesn't happen?

https://github.com/msys2/MINGW-packages/blob/master/mingw-w64-emscripten/PKGBUILD

furthermore, if PKGBUILD will be changed, I think you should remove the installation of file /clang64/share/licenses/LICENSE, which maybe is related to this issue: msys2/MSYS2-packages#5122

Expected behavior

It'd compile fine

Actual behavior

LLVM crashes
