Add asm versions of fmod(), fmodf() and fmodl() on amd64. Add asm
versions of fmodf() amd fmodl() on i387. fmod is similar to remainder, and the C versions are 3 to 9 times slower than the asm versions on x86 for both, but we had the strange mixture of all 6 variants of remainder in asm and only 1 of 6 variants of fmod in asm.
