  Log Message:
  -----------
  Sema: add support for `__attribute__((__swift_objc_members__))`

This adds the `__swift_objc_members__` attribute to the semantic
analysis.  It allows for annotating ObjC interfaces to provide Swift
semantics indicating that the types derived from this interface will be
back-bridged to Objective-C to allow interoperability with Objective-C
and Swift.

This is based on the work of the original changes in
