Douglas Gregor 4bd90e53c2 Eliminate QualifiedDeclRefExpr, which captured the notion of a
qualified reference to a declaration that is not a non-static data
member or non-static member function, e.g., 

  namespace N { int i; }
  int j = N::i;

Instead, extend DeclRefExpr to optionally store the qualifier. Most
clients won't see or care about the difference (since
QualifierDeclRefExpr inherited DeclRefExpr). However, this reduces the
number of top-level expression types that clients need to cope with,
brings the implementation of DeclRefExpr into line with MemberExpr,
and simplifies and unifies our handling of declaration references.

Extended DeclRefExpr to (optionally) store explicitly-specified
template arguments. This occurs when naming a declaration via a
template-id (which will be stored in a TemplateIdRefExpr) that,
following template argument deduction and (possibly) overload
resolution, is replaced with a DeclRefExpr that refers to a template
specialization but maintains the template arguments as written.

John McCall fc93cf9777 When building types from declarators, instead of building two types (one for
the DeclaratorInfo, one for semantic analysis), just build a single type whose
canonical type will reflect the semantic analysis (assuming the type is
well-formed, of course).

To make that work, make a few changes to the type system:
* allow the nominal pointee type of a reference type to be a (possibly sugared)
  reference type.  Also, preserve the original spelling of the reference type.
  Both of these can be ignored on canonical reference types.
* Remove ObjCProtocolListType and preserve the associated source information on
  the various ObjC TypeLocs.  Preserve the spelling of protocol lists except in
  the canonical form.
* Preserve some level of source type structure on parameter types, but
  canonicalize on the canonical function type.  This is still a WIP.

Drops code size, makes strides towards accurate source location representation,
slight (~1.7%) progression on Cocoa.h because of complexity drop.

Douglas Gregor d019ff686c When building and instantiating a template-id reference expression, such as
N::f<int>

keep track of the full nested-name-specifier. This is mainly QoI and
relatively hard to test; will try to come up with a printing-based
test once we also retain the explicit template arguments past overload
resolution.

Eli Friedman 06ed2a5c94 Remove default argument for ImpCastExprToType. Add appropriate argument
to all callers.  Switch a few other users of CK_Unknown to proper cast 
kinds.

Note that there are still some situations where we end up with 
CK_Unknown; they're pretty easy to find with grep. There 
are still a few missing conversion kinds, specifically 
pointer/int/float->bool and the various combinations of real/complex 
float/int->real/complex float/int.

Chris Lattner bd19b18100 Implement PR5242: don't desugar a type more than once in a diagnostic. This
implements a framework that allows us to use information about previously
substituted values to simplify subsequent ones.  Maybe this would be useful
for C++'y stuff, who knows.  We now get:

t.c:4:21: error: invalid operands to binary expression ('size_t' (aka 'unsigned long *') and 'size_t')
  return (size_t) 0 + (size_t) 0;
         ~~~~~~~~~~ ^ ~~~~~~~~~~

John McCall cebee16bc0 When performing template-substitution into a type, don't just replace the
TemplateTypeParmType with the substituted type directly;  instead, replace it
with a SubstTemplateTypeParmType which will note that the type was originally
written as a template type parameter.  This makes it reasonable to preserve
source information even through template substitution.

Also define the new SubstTemplateTypeParmType class, obviously.

For consistency with current behavior, we stringize these types as if they
were the underlying type.  I'm not sure this is the right thing to do.
At any rate, I paled at adding yet another clause to the don't-desugar 'if'
statement, so I extracted a function to do it.  The new function also does
The Right Thing more often, I think:  e.g. if we have a chain of typedefs
leading to a vector type, we will now desugar all but the last one.
