This seems to negatively affect compile time onsome ObjC tests (which use a lot of partial diagnostics I assume). I have to come up with a way to keep them inline without including Diagnostic.h everywhere. Now adding a new diagnostic requires a full rebuild of e.g. the static analyzer which doesn't even use those diagnostics. This reverts commit 6496bd10dc3a6d5e3266348f08b6e35f8184bc99. This reverts commit 7af19b817ba964ac560b50c1ed6183235f699789. This reverts commit fdd15602a42bbe26185978ef1e17019f6d969aa7. This reverts commit 00bd44d5677783527d7517c1ffe45e4d75a0f56f. This reverts commit ef9b60ffed980864a8db26ad30344be429e58ff5. llvm-svn: 150006
