Stefan Liebler 914a4e0557 S390: Refactor strcpy ifunc handling. 
The ifunc handling for strcpy is adjusted in order to omit ifunc
variants if those will never be used as the minimum architecture level
already supports newer CPUs by default.
Glibc internal calls will then also use the "newer" ifunc variant.

Note: The fallback s390-32/s390-64 ifunc variants with mvst instruction
are now moved to the unified strcpy-z900.S file which can be used for
31/64bit. The s390-32/s390-64 files multiarch/strcpy.c and strcpy.S
are deleted.

ChangeLog:

	* sysdeps/s390/multiarch/Makefile
	(sysdep_routines): Remove strcpy variants.
	* sysdeps/s390/Makefile (sysdep_routines): Add strcpy variants.
	* sysdeps/s390/multiarch/ifunc-impl-list.c
	(__libc_ifunc_impl_list): Refactor ifunc handling for strcpy.
	* sysdeps/s390/multiarch/strcpy-vx.S: Move to ...
	* sysdeps/s390/strcpy-vx.S: ... here and adjust ifunc handling.
	* sysdeps/s390/multiarch/strcpy.c: Move to ...
	* sysdeps/s390/strcpy.c: ... here and adjust ifunc handling.
	* sysdeps/s390/ifunc-strcpy.h: New file.
	* sysdeps/s390/s390-64/strcpy.S: Move to ...
	* sysdeps/s390/strcpy-z900.S: ... here and adjust to be usable
	for 31/64bit and ifunc handling.
	* sysdeps/s390/s390-32/multiarch/strcpy.c: Delete file.
	* sysdeps/s390/s390-64/multiarch/strcpy.c: Likewise.
	* sysdeps/s390/s390-32/strcpy.S: Likewise.
