rs6000: Expand fmod and remainder when built with fast-math [PR97142]
fmod/fmodf and remainder/remainderf could be expanded instead of library
call when fast-math build, which is much faster.
fmodf:
fdivs f0,f1,f2
friz f0,f0
fnmsubs f1,f2,f0,f1
remainderf:
fdivs f0,f1,f2
frin f0,f0
fnmsubs f1,f2,f0,f1
SPEC2017 Ofast P8LE: 511.povray_r +1.14%, 526.blender_r +1.72%
