Add support for __builtin_[max|min] which has below prototype:
A __builtin_max (A1, A2, A3, ...)
All arguments must have the same type; they must all be float, double, or long double.

Internally use SelectCC to get the result, and depends on D122462 <https://reviews.llvm.org/D122462> to work properly for ppcf128.
