This patch add a optimized llround/llroundf implementation for POWER8
using the new Move From VSR Doubleword instruction to gains some
cycles from FP to GRP register move.
In sysdeps/powerpc/powerpc64/fpu/multiarch/s_llround.c
in libc_ifunc() should it end as : __llround_ppc64); instead of : __llround_power8); for default.
