Compiling two or more C files with clang-cl generates the following linker error, if they inlcude `intrin.h`:
```
lld-link: error: duplicate symbol: __inbyte

This issue was introduced by the following commit: https://github.com/llvm/llvm-project/commit/348240362f9673c824c0ad22fd9e13ae3f937864
I think `inline` is not a valid keyword here. And due to functions being declared previously in intrin.h, the static keyword has no effect.
Other definitions in this header use `__inline__` instead. This fixes the issue for me.
