Comment diagnostics: \return in void function: specialize diagnostic text for
ObjC methods.

Comment diagnostics: warn on duplicate \brief and \return commands.

Doxygen manual claims that multiple \brief or \returns commands will be merged
together, but actual behavior is different (second \brief command becomes a
part of a discussion, second \returns becomes a "Returns: blah" paragraph on
its own).  Anyway, it seems to be a bad idea to use multiple \brief or \returns
commands in a single command.

[ms-inline asm] Pass Tokens to Sema and store them in the AST.  No functional
change intended.  No test case as there's no real way to test at this time.

For global record types, the self reference checker was called twice, resulting
in duplicate -Wuninitialized warnings.  Change so that only the check in
TryConstructorInitialization() will be used and a single warning be emitted.

[analyzer] Ignore OS X 10.8's annotations for NSMakeCollectable.

The frameworks correctly use the 'cf_consumed' and 'ns_returns_retained'
attributes for NSMakeCollectable, but we can model the behavior under
garbage collection more precisely than that.

No functionality change.

[analyzer] Add plist output checks for all four "path notes" tests.

No functionality change, but from now on, any new path notes should be
tested both with plain-text output (for ease of human auditing) and with
plist output (to ensure control flow and events are being correctly
represented in Xcode).

Refactor checks for unevaluated contexts into a common utility function.

The one caller that's surrounded by nearby code manipulating the underlying
evaluation context list is left unmodified for readability.

[analyzer] Add a checker to manage dynamic type propagation.

Instead of sprinkling dynamic type info propagation throughout
ExprEngine, the added checker would add the more precise type
information on known APIs (Ex: ObjC alloc, new) and propagate
the type info in other cases (ex: ObjC init method, casts (the second is
not implemented yet)).

Add handling of ObjC alloc, new and init to the checker.

[analyzer] Dynamic type info - propagate through implicit casts.

I currently have a bit of redundancy with the cast kind switch statement
inside the ImplicitCast callback, but I might be adding more casts going
forward.

[analyzer] DynTypes: Add a test for improper cast performed by  user.

Dynamic type inference does the right thing in this case. However, as
Jordan suggested, it would be nice to add a warning here as well.

Make sure when we get the replacement type for a template argument
