Iterate on sema for :? in Objective-C:
- Follow C99 behavior of using other operand type when one of
operands is a null pointer constant.
- Fix overenthusiastic devolving of any Objective-C types to id:
o If either operand has an Objective-C object type then:
- If both operands are interfaces and either operand can be
assigned to the other, use that type as the composite type.
- Otherwise, if either type is id, use id as the composite type.
- Otherwise, warn about incompatible types and use id as the
composite type.
- Return handling of qualified idea to separate test following
general pointer type checking.
o Upgraded from old code to allow devolving to id (without warning,
which matches GCC).
- <rdar://problem/6212771>
Add test case for issues fixed above, XFAIL though because it exposed
a new issue in property handling.
