* SPARC: reworked 64-bit comparisons so their result is always in flags. Comparisons are emitted as subtractions, sides are optionally swapped to avoid using Z flag (since it is not set correctly in multi-word subtraction). This generates significantly shorter code: when both sides are in registers it is just 3 instructions for equal/unequal and 2 instructions otherwise.
