Silviu Baranga ebacf44320 [InstCombine] Teach instcombine not to create extra PHI nodes when folding GEPs ... Summary: InstCombine tries to transform GEP(PHI(GEP1, GEP2, ..)) into GEP(GEP(PHI(...)) when possible. However, this may leave the old PHI node around. Even if we do end up folding the GEPs, having an extra PHI node might not be beneficial. This change makes the transformation more conservative. We now only do this if the PHI has only one use, and can therefore be removed after the transformation.
