In objc mode, every identifier in a cast expression was using doing a
type looking using getTypeName() and every property access was using
NextToken() to do lookahead to see if the identifier is followed by
a '.'. Rearrange this code to not need lookahead and only do the
type lookup if we have "identifier." in the token stream. Also
improve a diagnostic a bit.

Migrate Sema::ActOnCallExpr to Sema::FixOverloadedFunctionReference,
so that we maintain better source information after template argument
deduction and overloading resolves down to a specific

FixOverloadedFunctionReference didn't cope with.
(Finally) added a test case that puts together this change with the
DeclRefExpr change to (optionally) include nested-name-specifiers and
explicit template argument lists.

Remove OriginalTypeParmDecl; the original type is the one specified
in the DeclaratorInfo, if one is present.
Preserve source information through template instantiation. This is made
more complicated by the possibility that ParmVarDecls don't have DIs, which

Also preserve source information for function parameters in ObjC method
declarations.

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.

Fix integer overflow in PCHReader when reading the length of an
identifier. This caused a crash when reading PCH files that contained
long identifier names.
The issue is that 'StrLenPtr' was previously a 'const char *', meaning
the byte loaded from it would be interpretted as a signed integer. If
the topmost bit was set, conversion to 'unsigned' would extend that
bit, causing an overflow.
The solution is to make 'StrLenPtr' an 'unsigned char *', always
treating the value as an unsigned integer.

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.
