Change Details

The common version is much longer then the 2 instructions they should be. Replace with a builtin that generates an fmadd + return.

Some of the functions in msun can be implemented using a compiler builtin function to generate a small number of instructions. Implement this support in fma, fmax, fmin, and sqrt on arm64. Care must be taken as the builtin can be implemented as a function call on some architectures that lack direct support. In these cases we need to use the original code path.
