[analyzer] Make Malloc Checker optimistic in presence of inlining.
(In response of Ted's review of r150112.)
This moves the logic which checked if a symbol escapes through a
parameter to invalidateRegionCallback (instead of post CallExpr visit.)
To accommodate the change, added a CallOrObjCMessage parameter to
checkRegionChanges callback.
