The problem this change addresses is that we treat __is_pod and
__is_empty as keywords in C++, because they are built-in type traits
in GCC >= 4.3. However, GNU libstdc++ 4.2 (and possibly earlier
versions) define implementation-detail struct templates named __is_pod
and __is_empty. 

This commit solves the problem by recognizing

  struct __is_pod

and

  struct __is_empty

as special token sequences. When one of these token sequences is
encountered, the keyword (__is_pod or __is_empty) is implicitly
downgraded to an identifier so that parsing can continue. This is an
egregious hack, but it has the virtue of "just working" whether
someone is using libstdc++ 4.2 or not, without the need for special
flags.

things, this means that we can properly cope with member access

involve qualified names, e.g., x->Base::f. We now maintain enough
information in the AST to compare the results of the name lookup of
"Base" in the scope of the postfix-expression (determined at template
definition time) and in the type of the object expression.

where t has a dependent type. We save the nested-name-specifier in the
CXXUnresolvedMemberExpr then, during instantiation, substitute into
the nested-name-specifier with the (transformed) object type of t, so
that we get name lookup into the type of the object expression.

Note that we do not yet retain information about name lookup into the
lexical scope of the member access expression, so several regression
tests are still disabled.

  x->Base::f

We no longer try to "enter" the context of the type that "x" points
to. Instead, we drag that object type through the parser and pass it
into the Sema routines that need to know how to perform lookup within
member access expressions.

We now implement most of the crazy name lookup rules in C++
[basic.lookup.classref] for non-templated code, including performing
lookup both in the context of the type referred to by the member
access and in the scope of the member access itself and then detecting
ambiguities when the two lookups collide (p1 and p4; p3 and p7 are
still TODO). This change also corrects our handling of name lookup
within template arguments of template-ids inside the
nested-name-specifier (p6; we used to look into the scope of the
object expression for them) and fixes PR4703.

I have disabled some tests that involve member access expressions
where the object expression has dependent type, because we don't yet
have the ability to describe dependent nested-name-specifiers starting
with an identifier.

Also fix a checker context bug: the Dst set is not always empty initially. 
Because in GRExprEngine::CheckerVisit(), *CurrSet is used repeatedly. 
So we removed the Dst.empty() condition in ~CheckerContext() when deciding
whether to do autotransision.
