We are missing the most of the unsigned CMove match rules on sparc.

EVALUATION Sparc was missing the unsigned compare cmove patterns which could be emitted as a result of some optimizations which are currently guarded under AggressiveOpts. The fix is simply to add these patterns. Tested with new test case.
