powerpc: Add a POWER8-optimized version of cosf()
This implementation is based on the one already used at sysdeps/powerpc/powerpc64/fpu/multiarch/s_sinf-power8.S. * sysdeps/powerpc/powerpc64/fpu/multiarch/Makefile [$(subdir) = math] (libm-sysdep_routines): Add s_cosf-power8 and s_cosf-ppc64. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_cosf-power8.S: New file. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_cosf-ppc64.c: Likewise. * sysdeps/powerpc/powerpc64/fpu/multiarch/s_cosf.c: Likewise. * sysdeps/powerpc/powerpc64/power8/fpu/s_cosf.S: Likewise.
