Implement type checking of Objective-C property attributes.
- readonly and readwrite are mutually exclusive.
- assign, copy, and retain are mutually exclusive.
- copy and retain are invalid on non-object types.
- Warn about using default 'assign' property on object types
(attempting to follow gcc behavior).
