powerpc: Use default strcpy optimization for POWER7
This patches uses the default strcpy/stpcpy implementation for POWER7/PPC64. This is faster in mostly inputs for benchtests and for multiarch the implementation uses the POWER7 strlen and memcpy. * string/stpcpy.c (__stpcpy): Use STPCPY to redefine symbol name and cleanup macro usage. * string/strcpy.c (strcpt): Use STRCPY to redefine symbol name. * sysdeps/powerpc/powerpc64/multiarch/stpcpy-power7.S: Remove file. * sysdeps/powerpc/powerpc64/multiarch/stpcpy-ppc64.S: Likewise. * sysdeps/powerpc/powerpc64/multiarch/strcpy-power7.S: Likewise. * sysdeps/powerpc/powerpc64/multiarch/strcpy-ppc64.S: Likewise. * sysdeps/powerpc/powerpc64/power7/stpcpy.S: Likewise. * sysdeps/powerpc/powerpc64/power7/strcpy.S: Likewise. * sysdeps/powerpc/powerpc64/power7/strcpy.c: Likewise. * sysdeps/powerpc/powerpc64/stpcpy.S: Likewise. * sysdeps/powerpc/powerpc64/strcpy.S: Likewise. * sysdeps/powerpc/powerpc64/multiarch/stpcpy.c [SHARED && IS_IN (libc)]: Include <string/strcpy.c>. * sysdeps/powerpc/powerpc64/multiarch/stpcpy.c [SHARED && IS_IN (libc)]: Include <string/stpcpy.c>. * sysdeps/powerpc/powerpc64/multiarch/stpcpy-power7.c: New file. * sysdeps/powerpc/powerpc64/multiarch/stpcpy-ppc64.c: Likewise. * sysdeps/powerpc/powerpc64/multiarch/strcpy-power7.c: Likewise. * sysdeps/powerpc/powerpc64/multiarch/strcpy-ppc64.c: Likewise. * sysdeps/powerpc/powerpc64/power7/strcpy.c: Likewise.
