LOG: [x86][Windows] Fix chromium build break
Windows does not support float C89 math functions like:
- acosf
- asinf
- atanf
- coshf
- sinhf
- tanhf
These 6 libfuncs need to be type promoted.

This PR fixes the bug introduced by https://github.com/llvm/llvm-project/pull/98949

Added: 
    

Modified: 
    llvm/lib/Target/X86/X86ISelLowering.cpp
    llvm/test/CodeGen/X86/fp-strict-libcalls-msvc32.ll

Removed:
