70cd1769 - [libc][math] Do not use __builtin_round* with clang on x86 by default. (#220739)

[libc][math] Do not use __builtin_round* with clang on x86 by default. (#220739) `__builtin_round`/`__builtin_roundf` expansion for x86-64 using SSE4.1 rounding instruction by clang is only correct for the default rounding mode. See https://github.com/llvm/llvm-project/issues/140252
