[SelectionDAGBuilder] Add masked loads to PendingLoads rather than calling DAG.setRoot.
Masked loads are calling DAG.getRoot rather than calling SelectionDAGBuilder::getRoot, which means the PendingLoads weren't emptied to update the root and create any needed TokenFactor. So it would be incorrect to call setRoot for the masked load.
This patch instead adds the masked load to PendingLoads so that the root doesn't get update until a store or scatter or something happens.. Alternatively, we could call SelectionDAGBuilder::getRoot before it, but that would create unnecessary serialization.
