Optimize mempcpy on sparc.
* sysdeps/sparc/sparc32/memcpy.S: Implement mempcpy using a stub
that branches into memcpy.
* sysdeps/sparc/sparc64/memcpy.S: Likewise.
* sysdeps/sparc/sparc64/multiarch/memcpy-niagara1.S: Likewise.
* sysdeps/sparc/sparc64/multiarch/memcpy-niagara2.S: Likewise.
* sysdeps/sparc/sparc64/multiarch/memcpy-ultra3.S: Likewise.
* sysdeps/sparc/sparc64/multiarch/memcpy.S: Add mempcpy multiarch
bits.
* sysdeps/sparc/sparc64/rtld-memcpy.c: Include generic mempcpy
implementation too.
* sysdeps/sparc/mempcpy.S: New file.
