complaint to a warning and providing a helpful node in the case where
the "template<>" header is redundant because the corresponding
template-id refers to an explicit specialization. C++0x might still
change this behavior, and existing practice is all over the place on
the number of "template<>" headers actually needed.

operand of an addressof operator, and so we should not treat it as an abstract
member-pointer expression and therefore suppress the implicit member access.
This is really a well-formedness constraint on expressions: a DeclRefExpr of
a FieldDecl or a non-static CXXMethodDecl (or template thereof, or unresolved
collection thereof) should not be allowed in an arbitrary location in the AST.
Arguably it shouldn't be allowed anywhere and we should have a different expr
node type for this. But unfortunately we don't have a good way of enforcing
this kind of constraint right now.

type and fixes a long-standing code gen. crash reported in
at least two PRs and a radar. (radar 7405040 and pr5025).
There are couple of remaining issues that I would like for
Ted. and Doug to look at:
Ted, please look at failure in Analysis/MissingDealloc.m.
I have temporarily added an expected-warning to make the
test pass. This tests has a declaration of 'SEL' type which
may not co-exist with the new changes.
Doug, please look at a FIXME in PCHWriter.cpp/PCHReader.cpp.
I think the changes which I have ifdef'ed out are correct. They
need be considered for in a few Indexer/PCH test cases.

- Several important FIXMEs related to whether arguments are expressions or external names, and the mangling of extern "C" names (c.f., PR5522).

into pretty much everything about overload resolution in order to wean
BuildDeclarationNameExpr off LookupResult::getAsSingleDecl(). Replace
UnresolvedFunctionNameExpr with UnresolvedLookupExpr, which generalizes the
idea of a non-member lookup that we haven't totally resolved yet, whether by
overloading, argument-dependent lookup, or (eventually) the presence of
a function template in the lookup results.
Incidentally fixes a problem with argument-dependent lookup where we were
still performing ADL even when the lookup results contained something from
a block scope.
Incidentally improves a diagnostic when using an ObjC ivar from a class method.
This just fell out from rewriting BuildDeclarationNameExpr's interaction with
lookup, and I'm too apathetic to break it out.
The only remaining uses of OverloadedFunctionDecl that I know of are in
TemplateName and MemberExpr.

The following attributes are currently supported in C++0x attribute
lists (and in GNU ones as well):
- align() - semantics believed to be conformant to n3000, except for
redeclarations and what entities it may apply to
- final - semantics believed to be conformant to CWG issue 817's proposed
wording, except for redeclarations
- noreturn - semantics believed to be conformant to n3000, except for
redeclarations
- carries_dependency - currently ignored (this is an optimization hint)

BasicStore. In this example, BasicStore would lose information about
the pointer in path after '*path++', causing the analyzer to falsely
flag a null dereference. This addresses <rdar://problem/7191542>.

name 'T' is looked up in the expression
t.~T()
Previously, we weren't looking into the type of "t", and therefore
would fail when T actually referred to an injected-class-name. Fixes
PR5530.

than tweaking existing ASTs, since we were (*gasp*) stomping on ASTs
within templates. I'm glad we found this little stick of TNT early...
