Adhemerval Zanella 6905656404 sparc: Implement memset/bzero ifunc selection in C
This patch refactor the SPARC64 ifunc selector to a C implementation.
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/Makefile
	[$(subdir) = string] (sysdep_routines): Add memset-ultra1.
	* sysdeps/sparc/sparc64/multiarch/Makefile [$(subdir) = string]
	(sysdep_routines): Add memset-ultra1.
	* sysdeps/sparc/sparc32/sparcv9/multiarch/memset-ultra1.S: New
	file.
	* sysdeps/sparc/sparc32/sparcv9/multiarch/memset.c: Likewise.
	* sysdeps/sparc/sparc32/sparcv9/multiarch/bzero.c: Likewise.
	* sysdeps/sparc/sparc64/multiarch/ifunc-memset.h: Likewise.
	* sysdeps/sparc/sparc64/multiarch/memset-ultra1.S: Likewise.
	* sysdeps/sparc/sparc64/multiarch/memset.c: Likewise.
	* sysdeps/sparc/sparc64/multiarch/bzero.c: Likewise.
	* sysdeps/sparc/sparc32/sparcv9/multiarch/memset.S: Remove file.
