Bjorn Pettersson 45efd4242c [DSE] Bugfix to avoid PartialStoreMerging involving non byte-sized stores ... Summary: The DeadStoreElimination pass now skips doing PartialStoreMerging when stores overlap according to OW_PartialEarlierWithFullLater and at least one of the stores is having a store size that is different from the size of the type being stored. This solves problems seen in https://bugs.llvm.org/show_bug.cgi?id=41949 for which we in the past could end up with mis-compiles or assertions. The content and location of the padding bits is not formally described (or undefined) in the LangRef at the moment. So the solution is chosen based on that we cannot assume anything about the padding bits when having a store that clobbers more memory than indicated by the type of the value that is stored (such as storing an i6 using an 8-bit store instruction).
