[PATCH GCC][6/6]Restrict predcom using register pressure information

Hi, This patch restricts predcom pass using register pressure information. In case of high register pressure, we now prune additional chains as well as disable unrolling in predcom. In generally, I think this patch set is useful. Bootstrap and test on x86_64 ongoing. Any comments? Thanks, bin 2
