When computing the use set of a store, we need to add the store to the write set prior to iterating over later instructions. Otherwise, if there is a later aliasing load of that store, that load will not be tagged as a use, and bad things will happen. trackUsesOfI still adds later dependent stores of an instruction to that instruction's write set, but it never sees the original instruction, and so when tracking uses of a store, the store must be added to the write set by the caller. Fixes PR16834. llvm-svn: 188329
