x86-64: Add FMA multiarch functions to libm
This patch adds multiarch functions optimized with -mfma -mavx2 to libm.
e_pow-fma.c is compiled with $(config-cflags-nofma) due to PR 19003.
* sysdeps/x86_64/fpu/multiarch/Makefile (libm-sysdep_routines):
Add e_exp-fma, e_log-fma, e_pow-fma, s_atan-fma, e_asin-fma,
e_atan2-fma, s_sin-fma, s_tan-fma, mplog-fma, mpa-fma,
slowexp-fma, slowpow-fma, sincos32-fma, doasin-fma, dosincos-fma,
halfulp-fma, mpexp-fma, mpatan2-fma, mpatan-fma, mpsqrt-fma,
and mptan-fma.
