powerpc: Use generic wcscpy optimization
This patch removes the power6 wcscpy optimization and uses generic implementation instead. Currently, both power6 and power7 IFUNC variant resulting binary are essentially the same and the generic implementation with unrolling loop set to 8 also results in similar performance. Checked on powerpc64-linux-gnu. * sysdeps/powerpc/Makefile [$(subdir) == wcsmbs] (CFLAGS-wcscpy.c): New rule. * sysdeps/powerpc/power6/wcscpy.c: Remove file. * sysdeps/powerpc/powerpc32/power4/multiarch/wcscpy-power6.c: Likewise. * sysdeps/powerpc/powerpc32/power4/multiarch/wcscpy-power7.c: Likewise. * sysdeps/powerpc/powerpc32/power4/multiarch/wcscpy-ppc32.c: Likewise. * sysdeps/powerpc/powerpc32/power4/multiarch/wcscpy.c: Likewise. * sysdeps/powerpc/powerpc64/multiarch/wcscpy-power6.c: Likewise. * sysdeps/powerpc/powerpc64/multiarch/wcscpy-power7.c: Likewise. * sysdeps/powerpc/powerpc64/multiarch/wcscpy-ppc64.c: Likewise. * sysdeps/powerpc/powerpc64/multiarch/wcscpy.c: Likewise. * sysdeps/powerpc/powerpc64/power6/wcscpy.c: Likewise. * sysdeps/powerpc/powerpc32/power4/multiarch/Makefile [$(subdir) == wcsmbs] (sysdeps_routines): Remove wcscpy-power6 and wcscpy-power7. (CFLAGS-wcscpy-power7.c, CFLAGS-wcscpy-power6.c): Remove rule. * sysdeps/powerpc/powerpc64/multiarch/Makefile: Likewise. * sysdeps/powerpc/powerpc32/power4/multiarch/ifunc-impl-list.c: Remove wcscpy optimizations. * sysdeps/powerpc/powerpc64/multiarch/ifunc-impl-list.c: Likewise.
