PowerPC64 strncpy, stpncpy and strstr fixes
Makes __stpncpy_power8 call __memset_power8 directly rather than via an IFUNC. Fixes a missing _mcount, and removes some redundant NOPS. The *_is_local defines are also used in a followup patch. * sysdeps/powerpc/powerpc64/multiarch/strncpy-power7.S: Define MEMSET_is_local. * sysdeps/powerpc/powerpc64/multiarch/strncpy-power8.S: Likewise. * sysdeps/powerpc/powerpc64/multiarch/stpncpy-power7.S: Likewise. * sysdeps/powerpc/powerpc64/multiarch/stpncpy-power8.S: Likewise. Define MEMSET. * sysdeps/powerpc/powerpc64/multiarch/strstr-power7.S: Define STRLEN_is_local, STRNLEN_is_local, and STRCHR_is_local. * sysdeps/powerpc/powerpc64/power7/strstr.S: Likewise. Don't add nop after local calls. * sysdeps/powerpc/powerpc64/power7/strncpy.S: Define MEMSET_is_local. Don't add nop after local call. * sysdeps/powerpc/powerpc64/power8/strncpy.S: Likewise. Add missing CALL_MCOUNT.
