Matt Wala 1849093f7b [Scalarizer] Fix potential for stale data in Scattered across invocations ... Summary: Scalarizer has two data structures that hold information about changes to the function, Gathered and Scattered. These are cleared in finish() at the end of runOnFunction() if finish() detects any changes to the function. However, finish() was checking for changes by only checking if Gathered was non-empty. The function visitStore() only modifies Scattered without touching Gathered. As a result, Scattered could have ended up having stale data if Scalarizer only scalarized store instructions. Since the data in Scattered is used during the execution of the pass, this introduced dangling pointer errors. The fix is to check whether both Scattered and Gathered are empty before deciding what to do in finish().
