Chris Lattner 2ba5ca9d4f Improve the diagnostic emitted when an unused ObjC property getter 
is found.  Instead of complaining about a generic "unused expr",
emit:
t.m:7:3: warning: property access result unused - getters should not have side effects

While objc property getters *could* have side effects, according to
the language best practices, they *shouldn't*.  Hopefully the
diagnostic now gets this across.
