sparc: Implement memcpy/mempcpy ifunc selection in C
This patch refactor the SPARC64 ifunc selector to a C implementation. The x86_64 implementation is used as default, which resulted in common definitions (ifunc-init.h) used on both architectures. No functional change is expected, including ifunc resolution rules. Checked on sparc64-linux-gnu, sparcv9-linux-gnu and x86_64-linux-gnu. * sysdeps/sparc/sparc32/sparcv9/multiarch/memcpy-ultra1.S: New file. * sysdeps/sparc/sparc32/sparcv9/multiarch/memcpy.c: Likewise. * sysdeps/sparc/sparc32/sparcv9/multiarch/mempcpy.c: Likewise. * sysdeps/sparc/sparc64/multiarch/ifunc-memcpy.h: Likewise. * sysdeps/sparc/sparc64/multiarch/memcpy-ultra1.S: Likewise. * sysdeps/sparc/sparc64/multiarch/memcpy.c: Likewise. * sysdeps/sparc/sparc64/multiarch/mempcpy.c: Likewise. * sysdeps/sparc/sparc-ifunc.h (sparc_libc_ifunc_redirected): New macro. * sysdeps/sparc/sparc32/sparcv9/multiarch/Makefile [$(subdir) = string] (sysdep_routines): Add memcpy-ultra1. * sysdeps/sparc/sparc64/multiarch/Makefile [$(subdir) = string] (sysdep_routines): Add memcpy-ultra1. * sysdeps/sparc/sparc64/multiarch/memcpy.S: Remove file. * sysdeps/sparc/sparc32/sparcv9/multiarch/memcpy.S: Likewise.
