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

This attribute allows declarations to be restricted to the framework
itself, enabling Swift to remove the declarations when importing
libraries.  This is useful in the case that the functions can be
implemented in a more natural way for Swift.

This is based on the work of the original changes in
