[Openmp-commits] [openmp] [OpenMP][runtime] Fix comparison of integer expressions of different signedness (PR #128204)

[via Openmp-commits]

https://github.com/foxtran created https://github.com/llvm/llvm-project/pull/128204

This PR fixes warning which occurs if one compiles OpenMP runtime with GCC:
```
warning: comparison of integer expressions of different signedness: 'kmp_intptr_t' {aka 'long int'} and 'long unsigned int' [-Wsign-compare]
```
