ab7691c4ce Removing the notion of TargetAttributesSema and replacing it with one where the parsed attributes are responsible for knowing their target-specific nature, instead of letting Sema figure it out. This is necessary so that __has_attribute can eventually determine whether a parsed attribute applies to the given target or not.

3e424b5070 Teach the diagnostics engine about the Attr type to make reporting on semantic attributes easier (and not require hard-coded strings). This requires a getSpelling() function on the Attr class, which is table-driven. Updates a handful of cases where a hard-coded string was being used to test the functionality out. Updating associated test cases for the improved quoting.

cedaaea691 This diagnostic did not accept arguments, and did not have any test coverage. Parameterized the diagnostic, and made it more consistent with other attribute diagnostic wordings. Added test coverage. 
Since this warning was generalized, it was also given a sensible warning group flag and the corresponding test was updated to reflect this.

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.

f41cf7f10f Rename attribute 'objc_suppress_protocol_methods' to 'objc_protocol_requires_explicit_implementation'. 
That's a mouthful, and not necessarily the final name.  This also
reflects a semantic change where this attribute is now on the
protocol itself instead of a class.  This attribute will require
that a protocol, when adopted by a class, is explicitly implemented
by the class itself (instead of walking the super class chain).

Note that this attribute is not "done".  This should be considered
a WIP.
