Avoid performance penalty in sparc optimized memcpy/memset.
...
fmovd clears the current exception field in the %fsr, fsrc2
does not and therefore runs more efficiently on some cpus.
* sysdeps/sparc/sparc64/memcpy.S: Use fsrc2 to move 64-bit
values between float registers.
* sysdeps/sparc/sparc64/memset.S: Likewise.
* sysdeps/sparc/sparc64/multiarch/memcpy-niagara2.S: Likewise.
