* Fixed general peephole optimization of conditional jumps after r30446. It has been broken, since r30446 had added some IsJumpToLabel() checks, which tests for unconditional jump, but the optimization code expects also conditional jumps.

* Modified FindRegAlloc() to skip branch delay slots in the same way it is done in GetNextInstruction(). This fixes processing sequences "dealloc reg; branch reg,label; NOP; alloc reg" in BuildLabelTableAndFixRegAlloc(), deallocation is now correctly moved after branch. Before this change, the last allocation was ignored, and deallocation was moved forward until another instruction using reg was encountered.
