[Bug tree-optimization/43402] [4.5 Regression] dom1 miscompiles binary search

Hmm, I wonder how that could cause the bug.  Probably because we can't rely
on SSA form being uptodate during cfgcleanup, and hence looking up PHI
arguments is wrong, at least for those SSA names that are registered for
updating.
