Move two key ObjC typechecks from Sema::CheckPointerTypesForAssignment() to ASTContext::mergeTypes().
This allows us to take advantage of the recursion in ASTContext::mergeTypes(), removing some bogus warnings.
This test case I've added includes an example where we still warn (and GCC doesn't). Need to talk with folks and decide what to do. At this point, the major bogosities should be fixed.

Add another IntExprEvaluator::Success overload to suck up remained of
...
manual setting of the Result.
- Idiom now enforces that result will always have correct width and
type; this exposed three new bugs:
o Enum constant decl value can have different width than type
(PR3173).
o EvaluateInteger should not run an IntExprEvaluator over
non-integral expressions.
o FloatExprEvaluate was not handling casts correctly (it was
evaluating the cast in the IntExprEvaluator!).
