Philip Reames 457e69f814 [SimplifyCFG] Fix a cost modeling oversight in branch commoning ...

The cost modeling was not accounting for the fact we were duplicating the instruction once per predecessor.  With a default threshold of 1, this meant we were actually creating #pred copies.

Adding to the fun, there is *absolutely no* test coverage for this.  Simply bailing for more than one predecessor passes all checked in tests.
