The checking of the accessors generated by a macro against the documented set of accessors for the macro is slightly too strict and produces misleading error messages. Make the check slightly looser in the case where an observer-producing macro (such as `@ObservationIgnored`) is applied to a computed property. Here, we would diagnose that the observer did not in fact produce any observers, even though it couldn't have: computed properties don't get observers. Remove the diagnostic in this case. While here, add some tests and improve the wording of diagnostics a bit. Fixes rdar://113710199.
