Add synthesized property methods to protocols and categories in Sema.
...
- It is not clear that this is the right approach, but this is at
least consistent with how interfaces are handled.
- This means NeXT now emits the correct metadata for properties in
protocols.
- This currently introduces a spurious warning involving inherited
properties in protocols or categories; however, it also fixes some
situations where we were failing to emit a warning. I will scrub
this code tomorrow and fix this issue as well as number of other
missed warnings / error situations that appear to exist.
