Owen Anderson d5f8684b16 It is possible for SimplifyCFG to cause PHI nodes to become redundant too late in the optimization 
pipeline to be caught by instcombine, and it's not feasible to catch them in SimplifyCFG because the
use-lists are in an inconsistent state at the point where it could know that it need to simplify them.
Instead, have CodeGenPrepare look for trivially redundant PHIs as part of its general cleanup effort.
