Anna Zaks 150843b87e [analyzer] ObjC Inlining: Start tracking dynamic type info in the GDM
In the following code, find the type of the symbolic receiver by
following it and updating the dynamic type info in the state when we
cast the symbol from id to MyClass *.

  MyClass *a = [[self alloc] init];
  return 5/[a testSelf];

Jordan Rose 6a97d92ef5 [analyzer] Don't try to inline if there's no region for a message receiver.
While usually we'd use a symbolic region rather than a straight-up Unknown,
we can still generate unknowns via array subscripts with symbolic indexes.
(And if this ever changes in the future, we still shouldn't crash.)

Anna Zaks 63282aefb9 [analyzer] Very simple ObjC instance method inlining
- Retrieves the type of the object/receiver from the state.
- Binds self during stack setup.
- Only explores the path on which the method is inlined (no
bifurcation to explore the path on which the method is not inlined).

Disabled by default for now.

Anna Zaks 8e3b260313 [analyzer] Another false positive in Class method inlining.
We are currently not setting the self object to the calling class object
during inlining nor do we reason about [AAA class].

Anna Zaks 83f1495fcb [analyzer] Inline ObjC class methods.
- Some cleanup(the TODOs) will be done after ObjC method inlining is
complete.
- Simplified CallEvent::getDefinition not to require ISDynamicDispatch
parameter.
- Also addressed Jordan's comments from r160530.
