powerpc: refactor memcpy and mempcpy IFUNC.
Clean up the IFUNC implementations for powerpc in order to remove unneeded macro definitions. Tested on ppc64le with and without --disable-multi-arch flag. * sysdeps/powerpc/powerpc64/multiarch/memcpy-a2.S: Define the implementation-specific function name and remove unneeded macros definition. * sysdeps/powerpc/powerpc64/multiarch/memcpy-cell.S: Likewise. * sysdeps/powerpc/powerpc64/multiarch/memcpy-power4.S: Likewise. * sysdeps/powerpc/powerpc64/multiarch/memcpy-power6.S: Likewise. * sysdeps/powerpc/powerpc64/multiarch/memcpy-power7.S: Likewise. * sysdeps/powerpc/powerpc64/multiarch/memcpy-ppc64.S: Likewise. * sysdeps/powerpc/powerpc64/multiarch/mempcpy-power7.S: Likewise. * sysdeps/powerpc/powerpc64/a2/memcpy.S: Set a default function name if not defined and pass as parameter to macros accordingly. * sysdeps/powerpc/powerpc64/cell/memcpy.S: Likewise. * sysdeps/powerpc/powerpc64/memcpy.S: Likewise. * sysdeps/powerpc/powerpc64/power4/memcpy.S: Likewise. * sysdeps/powerpc/powerpc64/power6/memcpy.S: Likewise. * sysdeps/powerpc/powerpc64/power7/memcpy.S: Likewise. * sysdeps/powerpc/powerpc64/power7/mempcpy.S: Likewise.
