[SPARC64]: Fix up copy_page just like clear_page.

- Do not save/restore existing TLB entries, that is
  expensive, complicated, and does not really help
  performance much at all.
- Only one unrolled loop for cheetah copy code.
- For spitfire, use %asi register for block commit
  handling so we do not need two copies of the code.
