2a9f539168 Fix bug in copying long constants to register pairs. We were getting
the top and bottom halves backwards...how embarrassing.
Support 'cast long to long' and other similar no-op casts to long.
Support 'ret long'.

       BB
   cond. branch

Implement some simple casts: integral, smaller than longs, and equal-width
 or narrowing only.

4d0cda4d5c This is a start on handling setcc instructions. As the comment notes, we
have no good way of handling this until the code generator is improved.
We should probably just emit V9 instructions in the meantime.

05b15fb075 TargetCacheInfo has been removed; its only uses were to propagate a constant
(16) into certain areas of the SPARC V9 back-end. I'm fairly sure the US IIIi's
dcache has 32-byte lines, so I'm not sure where the 16 came from. However, in
the interest of not breaking things any more than they already are, I'm going
to leave the constant alone.
