John Brawn f36d8dfcf7 [BasicAA] Use PhiValuesAnalysis if available when handling phi alias ... By using PhiValuesAnalysis we can get all the values reachable from a phi, so we can be more precise instead of giving up when a phi has phi operands. We can't make BaseicAA directly use PhiValuesAnalysis though, as the user of BasicAA may modify the function in ways that PhiValuesAnalysis can't cope with. For this optional usage to work correctly BasicAAWrapperPass now needs to be not marked as CFG-only (i.e. it is now invalidated even when CFG is preserved) due to how the legacy pass manager handles dependent passes being invalidated, namely the depending pass still has a pointer to the now-dead dependent pass.
