[DAGCombiner] When folding fold (sext/zext (and/or/xor (sextload/zextload x), cst)) -> (and/or/xor (sextload/zextload x), (sext/zext cst)) make sure we check the legality of the full extended load.
Summary:
If the load is already an extended load we should be using the memory VT for the legality check, not just the VT of the current extension.
I don't have a test case, just noticed it while investigating some load extension improvements.
