[libc][math] Refactor logf16 to header-only shared math ( #175408 )
...
## Summary
Following the discussion in the RFC [1], Refactors logf16 to a
header-only shared math.
[1]
https://discourse.llvm.org/t/rfc-make-clang-builtin-math-functions-constexpr-with-llvm-libc-to-support-c-23-constexpr-math-functions/86450
## Implementation
- Moved the core logic and lookup tables from `generic/logf16.cpp` to
`__support/math/logf16.h`
- Updated `generic/logf16.cpp` to include the new header and call
`internal::logf16`
- Updated `CMakeLists.txt` and `BUILD.bazel` to reflect the dependency
changes and new header library
Fix : https://github.com/llvm/llvm-project/issues/175367

[APFloat] Add exp function for APFloat::IEEESsingle using expf implementation from LLVM libc. ( #143959 )
...
Discourse RFC:
https://discourse.llvm.org/t/rfc-make-clang-builtin-math-functions-constexpr-with-llvm-libc-to-support-c-23-constexpr-math-functions/86450
- The implementation in LLVM libc is header-only.
- expf implementation in LLVM libc is correctly rounded for all rounding
modes.
- LLVM libc implementation will round to the floating point
environment's rounding mode.
- No cmake build dependency between LLVM and LLVM libc, only requires
LLVM libc source presents in llvm-project/libc folder.
