John McCall 9dd450bb78 Change all the Type::getAsFoo() methods to specializations of Type::getAs().
Several of the existing methods were identical to their respective
specializations, and so have been removed entirely.  Several more 'leaf'
optimizations were introduced.

The getAsFoo() methods which imposed extra conditions, like
getAsObjCInterfacePointerType(), have been left in place.

Douglas Gregor 87f5406081 When implicitly declaring operators new, new[], delete, and delete[],
give them the appropriate exception specifications. This,
unfortunately, requires us to maintain and/or implicitly generate
handles to namespace "std" and the class "std::bad_alloc". However,
every other approach I've come up with was more hackish, and this
standard requirement itself is quite the hack.

Fixes PR4829.

Fariborz Jahanian adcea10410 1) don't do overload resolution in selecting conversion
to pointer function for delete expression. 2)
Treat type conversion function and its 'const' version
as identical in building the visible conversion list.

Douglas Gregor ad8a336b40 Implement AST, semantics, and CodeGen for C++ pseudo-destructor
expressions, e.g.,

when p is a pointer to a scalar type. 

We don't currently diagnose errors when pseudo-destructor expressions
are used in any way other than by forming a call.

Douglas Gregor 2b6ca46c6b Improve template instantiation for member access expressions that
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.

Douglas Gregor b7bfe79412 Rewrite of our handling of name lookup in C++ member access expressions, e.g.,
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.
