  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.
