Use "strict" instead of "nopartial". Also make strictly not-introduced
share the same diagnostics as Obsolete and Unavailable.

An optional nopartial can be placed after the platform name.
int bar() __attribute__((availability(macosx,nopartial,introduced=10.12))
When deploying back to a platform version prior to when the declaration was
introduced, with 'nopartial', Clang emits an error specifying that the function
is not introduced yet; without 'nopartial', the behavior stays the same: the
declaration is `weakly linked`.
A member is added to the end of AttributeList to save the location of the
'nopartial' keyword. A bool member is added to AvailabilityAttr.
The diagnostics for 'nopartial' not-yet-introduced is handled in the same way as
we handle unavailable cases.

This warns when using decls that are not available on all deployment targets.
For example, a call to
- (void)ppartialMethod __attribute__((availability(macosx,introduced=10.8)));
will warn if -mmacosx-version-min is set to less than 10.8.
To silence the warning, one has to explicitly redeclare the method like so:
@interface Whatever(MountainLionAPI)
- (void)ppartialMethod;
@end
This way, one cannot accidentally call a function that isn't available
everywhere. Having to add the redeclaration will hopefully remind the user
to add an explicit respondsToSelector: call as well.
Some projects build against old SDKs to get this effect, but building against
old SDKs suppresses some bug fixes -- see http://crbug.com/463171 for examples.
The hope is that SDK headers are annotated well enough with availability
attributes that new SDK + this warning offers the same amount of protection
as using an old SDK.

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.

Language-design credit goes to a lot of people, but I particularly want
to single out Blaine Garst and Patrick Beard for their contributions.
Compiler implementation credit goes to Argyrios, Doug, Fariborz, and myself,
in no particular order.

string itself lives longer than the DelayedDiagnostic. Fixes a recent
use-after-free regression due to my availability attribute work.
