Add target hook to prevent folding some bitcasted loads. This is to avoid this transformation in some cases: fold (conv (load x)) -> (load (conv*)x) On architectures that don't natively support some vector loads efficiently casting the load to a smaller vector of larger types and loading is more efficient.
