[SPARC64]: Add prefetch support.
The implementation is optimal for UltraSPARC-III and later.
It will work, however suboptimally, on UltraSPARC-II and
be treated as a NOP on UltraSPARC-I.
It is not worth code patching this thing as the highest cost
is the code space, and code patching cannot eliminate that.
