There was no place in bytecode where annotations on properties without backing
fields could be stored to. Now they're written on a synthetic empty void method
with a special name ("propertyName$annotations").
(Annotations on properties cannot simply be written on getters in bytecode,
since a getter can have annotations of its own.)
