This revision is now accepted and ready to land.
LGTM, please make sure this doesn't break things as PRE in GVN is quite fragile :)
================
Comment at: lib/Transforms/Scalar/GVN.cpp:2224
VN.add(Phi, ValNo);
+ VN.eraseTranslateCacheEntry(ValNo, *CurrentBlock);
addToLeaderTable(ValNo, Phi, CurrentBlock);
