Re: [perl #36597] [PATCH]Dominance Frontiers

This patch adds a bb_remove_edge() function, and decouples unreachable blocks
from the CFG by removing their successor edges.
-----

I think this is the best way to handle unreachable blocks in the CFG,
other than removing them, which is an -O1 optimization.
