powerpc: Optimized strncat for POWER8
With new optimized strnlen for POWER8 [1], this patch adds strncat for power8 to make use of optimized strlen and strnlen. This is faster than POWER7 current implementation for larger strings. Tested on powerpc64 and powerpc64le. [1] https://sourceware.org/ml/libc-alpha/2017-03/msg00491.html * sysdeps/powerpc/powerpc64/multiarch/Makefile (sysdep_routines): Add strncat-power8. * sysdeps/powerpc/powerpc64/multiarch/strncat.c (strncat): Add __strncat_power8 to ifunc list. * sysdeps/powerpc/powerpc64/multiarch/ifunc-impl-list.c (strncat): Add __strncat_power8 to list of strncat functions. * sysdeps/powerpc/powerpc64/multiarch/strncat-power8.c: New file.
