This patch adds a check to optimize conditional branch (BC and BCn) based on a constant set by CRSET or CRUNSET. Other optimizers, such as block placement, may generate such code and hence I do this at the very end of the optimization in pre-emit peephole pass. A conditional branch based on a constant is eliminated or converted into unconditional branch. Also CRSET/CRUNSET is eliminated if the condition code register is not used by instruction other than the branch to be optimized.
