This revision is now accepted and ready to land.

The changes LGTM aside from a small wording nit with the documentation. The parser changes I asked about can be done in a follow-up to this patch.



================
Comment at: clang/include/clang/Basic/AttrDocs.td:3604-3606
+attribute appertains is imported as a new Swift type of the typedef's name.  The
+``swift-wrapper`` is the old name for this attribute which is kept for
+compatibility.  New uses should prefer the ``swift_newtype`` spelling.
----------------
For the new blurb about the deprecated name, how about:

Previously, the attribute was spelled `swift_wrapper`. While the behavior of the attribute is identical with either spelling, `swift_wrapper` is deprecated, only exists for compatibility purposes, and should not be used in new code.
