[PATCH] D26790: [X86] Add a hasOneUse check to selectScalarSSELoad to keep the same load from being folded multiple times

Given the problem with the chain I don't think I can gate this on any optimization flag. I think we need this check to be consistent with the behavior that OPC_CheckFoldableChainNode has for normal load during isel. That check makes sure all nodes preceeding the load up to the root have a single use. So adding the check here would ensure the same behavior.
