I don't want to push it quite yet as I wanted feedback to make sure
we don't actually do anything I'm not aware of with SSA_NAMES which
have the ABNORMAL_PHI flag set. Most of the code i can find in VRP
and vr-values appears to punt, so I presume not even considering
those names is fine?
This also seems like something that might be worth back-porting,
especially the hybrid pass parts...
Punting on the abnormals seems perfectly fine to me. They rarely, if
ever, provide information that improves optimization.
