[PATCH] D37381: Fix regression in special member definitions under SuppressAllDiagnostics

`make check` didn't regress from this.

This behavior difference is not observable from within Clang itself, only in external applications that use SuppressAllDiagnostics while forcing definition of implicit members.  Adding a test will require reproducing a chunk of the application code in the test suite to create the appropriate CompilerInstance.  I'd be happy to do that to keep this working in the future, but where would be the appropriate place?

BTW, I'd like to see this integrated in the `release_50` branch because this regression breaks my application that works with 3.6, 3.7, 3.8, 3.9, and 4.0.
