Conditions for warning:
1. the property is atomic
2. the current @implementation contains an @synthesize for the property
3. the current @implementation contains a hand-written setter XOR getter
4. the property is read-write
Cases marked WARN should warn one the following:
warning: Atomic property 'x' has a synthesized setter and a
manually-implemented getter, which may break atomicity.
warning: Atomic property 'x' has a synthesized getter and a
manually-implemented setter, which may break atomicity.
Cases not marked WARN only satisfy the indicated subset
of the conditions required to warn.
There should be 8 warnings.
