Aaron Ballman adf66b6174 Determine the attribute subject for diagnostics based on declarative information in DeclNodes.td. This greatly reduces the number of enumerated values used for more complex diagnostics; these are now only required when the "attribute only applies to" diagnostic needs to be generated manually as part of semantic processing. 
This also clarifies some terminology used by the diagnostic (methods -> Objective-C methods, fields -> non-static data members, etc).

Many of the tests needed to be updated in multiple places for the diagnostic wording tweaks. The first instance of the diagnostic for that attribute is fully specified and subsequent instances cut off the complete list (to make it easier if additional subjects are added in the future for the attribute).

Paul Robinson 41a2508e59 [PS4] Undo dialect tweak for Objective-C. 
In r267772, we had set the PS4's default dialect for both C and
Objective-C to gnu99.  Make that change only for C; we don't really
support Objective-C/C++ so there's no point fiddling the dialect.

Fariborz Jahanian c9e266b8cf [Objective-C]. This patch extends objc_bridge attribute to support objc_bridge(id). 
This means that a pointer to the struct type to which the attribute appertains 
is a CF type (and therefore an Objective-C object of some type), but not of any 
specific class. rdar://19157264

Fariborz Jahanian 953d18a988 Objective-C ARC. Under ARC, addition of 'bridge' attribute 
on CF type is not sufficient and bridge casting is
still required for proper ownership semantics.

Fariborz Jahanian 48a01cb5ec Objective-C arc [Sema]. Allow bridge cast of a qualified-id expression 
when bridged Objective-C type conforms to the protocols in CF types's
