LOG: [x86][Windows] Fix chromium build break (#101268)
Windows does not support float C89 math functions like:
- acosf
- asinf
- atanf
- coshf
- sinhf
- tanhf
All 6 are disabled in
[TargetLibraryInfo.cpp:293](https://github.com/llvm/llvm-project/blob/39e192b379362e9e645427631c35450d55ed517d/llvm/lib/Analysis/TargetLibraryInfo.cpp#L293C4-L296C41)
These 6 libfuncs need to be type promoted.
