[PATCH] D41177: [DAGCombine] Move AND nodes to multiple load leaves

https://reviews.llvm.org/rL320679 was reverted due to a miscompilation. I had made the false assumption that constant operands would have been narrowed. So now any OR and XOR nodes which use constant operands, which are wider than the mask, have their operand narrowed at the end of the process.
