Change our basic strategy for avoiding deprecation warnings when the decl use
appears in a deprecated context.  In the new strategy, we emit the warnings
as usual unless we're currently parsing a declaration, where "declaration" is
restricted to mean a decl group or a few special cases in Objective C.  If
we *are* parsing a declaration, we queue up the deprecation warnings until
the declaration has been completely parsed, and then emit them only if the
decl is not deprecated.
We also standardize the bookkeeping for deprecation so as to avoid special cases.

Refine codegen for non-virtual this adjustments for thunks.

Switch ParseStructDeclaration to a callback-based API.  This will make
it easier to track within Sema whether the parser is parsing a declaration.

Introduce a new class, UnqualifiedId, that provides a parsed
representation of a C++ unqualified-id, along with a single parsing
function (Parser::ParseUnqualifiedId) that will parse all of the
various forms of unqualified-id in C++.

Replace the representation of the declarator name in Declarator with
the new UnqualifiedId class, simplifying declarator-id parsing
considerably and providing more source-location information to
Sema. In the future, I hope to migrate all of the other
unqualified-id-parsing code over to this single representation, then
begin to merge actions that are currently only different because we
didn't have a unqualified notion of the name in the parser.

Remove GRExprEngine::CheckerVisitLocation().  It was only called in one place, so we inlined it in to GRExprEngine::EvalLocation().

Diagnose implementation of a property declared in a category
in its class implementation instead of crashing. Fixes radar 7350345.

When determining whether a reference to a static data member is an
integral constant expression, make sure to find where the initializer
was provided---inside or outside the class definition---since that can
affect whether we have an integral constant expression (and, we need
to see the initializer itself).

Within a template, qualified name lookup can refer to a non-dependent type
that is not known to be a base class at template definition time due
to some dependent base class. Treat qualified name lookup that refers
to a non-static data member or function as implicit class member
access when the "this" type would be dependent.
