5aa4ecfd0d sparc64: Add membar to Niagara2 memcpy code. 
This is the prevent previous stores from overlapping the block stores
done by the memcpy loop.

Based upon a glibc patch by Jose E. Marchesi

1b62ca7bf5 sparc64: Fix return value of Niagara-2 memcpy. 
It gets clobbered by the kernel's VISEntryHalf, so we have to save it
in a different register than the set clobbered by that macro.

The instance in glibc is OK and doesn't have this problem.

6f1d827f29 sparc64: Consistently use fsrc2 rather than fmovd in optimized asm. 
Because fsrc2, unlike fmovd, does not update the %fsr register.
