[DAGCombiner] isAllOnesConstantOrAllOnesSplatConstant(): look through bitcasts Summary: As pointed out in D46528, we errneously transform cases like `xor X, -1`, even though we use said function. It's because the `-1` is actually a bitcast there. So i think we can just look through it in the function.
