Intercept sizeof and alignof references before they get into ASTContext methods. This fixes a crash when writing sizeof(Incomplete&), and lets ASTContext's methods do the right thing for CodeGen, which fixes PR5590.

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.

Change CheckDeadStores to use Expr::isNullPointerConstant, which will correctly determine whether an expression is a null pointer constant.

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).

 - Sometimes we have to mangle things we wouldn't normally (e.g., because they appear in a template expression).

 - This also tidies up the predicate to be more obvious what is getting mangled.
