Bjorn Pettersson 72e765907f [ConstantFolding] Avoid assert when folding ptrtoint of vectorized GEP ... Summary: Got asserts in llvm::CastInst::getCastOpcode saying: `DestBits == SrcBits && "Illegal cast to vector (wrong type or size)"' failed. Problem seemed to be that llvm::ConstantFoldCastInstruction did not handle ptrtoint cast of a getelementptr returning a vector correctly. I assume such situations are quite rare, since the GEP needs to be considered as a constant value (base pointer being null). The solution used here is to simply avoid the constant fold of ptrtoint when the value is a vector. It is not supported, and by bailing out we do not fail on assertions later on.
