Fariborz Jahanian 19a08bbb9a Objective-C. No need to issue deprecated warning if deprecated method 
in class extension is being implemented in primary class implementation
(no overriding is involved).

Ted Kremenek b79ee57080 Implemented delayed processing of 'unavailable' checking, just like with 'deprecated'. 
Fixes <rdar://problem/15584219> and <rdar://problem/12241361>.

This change looks large, but all it does is reuse and consolidate
the delayed diagnostic logic for deprecation warnings with unavailability
warnings.  By doing so, it showed various inconsistencies between the
diagnostics, which were close, but not consistent.  It also revealed
some missing "note:"'s in the deprecated diagnostics that were showing
up in the unavailable diagnostics, etc.

This change also changes the wording of the core deprecation diagnostics.
Instead of saying "function has been explicitly marked deprecated"
we now saw "'X' has been been explicitly marked deprecated".  It
turns out providing a bit more context is useful, and often we
got the actual term wrong or it was not very precise
 (e.g., "function" instead of "destructor").  By just saying the name
of the thing that is deprecated/deleted/unavailable we define
this issue away.  This diagnostic can likely be further wordsmithed
to be shorter.

Fariborz Jahanian d91d21cc33 objective-C: Do not issue deprecated warning about implementation 
of a deprecated method in original class (or category), only
in overrides. // rdar://12717705

Fariborz Jahanian f021889036 -Wdeprecated warning to include reference (as a note) 
to the declaration in this patch. // rdar://10893232

Patrick Beard acfbe9e1f2 Added a new attribute, objc_root_class, which informs the compiler when a root class is intentionally declared. 
The warning this inhibits, -Wobjc-root-class, is opt-in for now. However, all clang unit tests that would trigger
the warning have been updated to use -Wno-objc-root-class. <rdar://problem/7446698>

Ted Kremenek 59b10db2bc After numerous requests, have Objective-C 'method declared here' notes mention the actual method. This looks better within an IDE, where text isn't always regurgitated in the presentation of a warning. Fixes radar 10914035.

Argyrios Kyrtzidis c281c96675 Implicitly assume that a ObjC category to an unavailable interface is also unavailable; 
only give an 'unavailable' error on the @implementation of the category. rdar://10234078
