Add semantic checking for template arguments that correspond to
non-type template parameters that are references to functions or
pointers to member functions. Did a little bit of refactoring so that
these two cases, along with the handling of non-type template
parameters that are pointers to functions, are handled by the same
path.
Also, tweaked FixOverloadedFunctionReference to cope with member
function pointers. This is a necessary step for getting all of the fun
member pointer conversions working outside of template arguments, too.

Semantic checking for template arguments that correspond to non-type

Add partial semantic checking of template arguments that are meant for
non-type template parameters of pointer-to-object and
pointer-to-function type. The most fun part of this is the use of
overload resolution to pick a function from the set of overloaded
functions that comes in as a template argument.
Also, fixed two minor bugs in this area:
- We were allowing non-type template parameters of type pointer to
void.
- We weren't patching up an expression that refers to an overloaded
function set via "&f" properly.
We're still not performing complete checking of the expression to be
sure that it is referring to an object or function with external
linkage (C++ [temp.arg.nontype]p1).

PTH: Replace ad hoc 'file name' -> 'PTH data' lookup table in the PTH file with an on-disk chained hash table. This data structure is implemented using templates, and will be used to replace similar data structures. This change leads to no visibile performance impact on Cocoa.h, but now we only pay a price for the table on order with the number of files accessed and not the number in the PTH file.

We handle indentation of decls better.
We Indent extern "C" { } stuff better.
We print out structure contents more often.
We handle pass indentation information into the statement printer, so that
nested things come out more indented.
We print out FieldDecls.
We print out Vars.
We print out namespaces.
We indent functions better.

Teach the type-id/expression disambiguator about different
disambiguation contexts, so that we properly parse template arguments
such as
A<int()>
as type-ids rather than as expressions. Since this can be confusing
(especially when the template parameter is a non-type template
parameter), we try to give a friendly error message.
Almost, eliminate a redundant error message (that should have been a
note) and add some ultra-basic checks for non-type template
arguments.

Start processing template-ids as types when the template-name refers
to a class template. For example, the template-id 'vector<int>' now
has a nice, sugary type in the type system. What we can do now:
- Parse template-ids like 'vector<int>' (where 'vector' names a
class template) and form proper types for them in the type system.
- Parse icky template-ids like 'A<5>' and 'A<(5 > 0)>' properly,
using (sadly) a bool in the parser to tell it whether '>' should
be treated as an operator or not.
This is a baby-step, with major problems and limitations:
- There are currently two ways that we handle template arguments
(whether they are types or expressions). These will be merged, and,
most likely, TemplateArg will disappear.
- We don't have any notion of the declaration of class template
specializations or of template instantiations, so all template-ids
are fancy names for 'int' :)

Make Sema::getTypeName return the opaque pointer of a QualType rather
than a Decl, which gives us some more flexibility to express the
results with the type system. There are no clients using this
flexibility yet, but it's meant to be able to describe qualified names
as written in the source (e.g., "foo::type") or template-ids that name
a class template specialization (e.g., "std::vector<INT>").
DeclSpec's TST_typedef has become TST_typename, to reflect its use to
describe types found by name (that may or may not be typedefs). The
type representation of a DeclSpec with TST_typename is an opaque
QualType pointer. All users of TST_typedef, both direct and indirect,
have been updated for these changes.
