definitions. We were rejecting tentative definitions of incomplete
(which is bad), and now we don't.

This fix is partial because we don't do the end-of-translation-unit
initialization for tentative definitions that don't ever have any
initializers specified.

context of a template-id for which we need to instantiate default
template arguments.

In the TextDiagnosticPrinter, don't suppress the caret diagnostic if
we are producing a non-note diagnostic that follows a note diagnostic
with the same location, because notes are (conceptually) a part of the
warning or error that comes before them.

only print the template instantiation backtrace for the first error.

Also, if a base class has failed to type-check during instantiation,
just drop that base class and continue on to check other base classes.

In the "template instantiation depth exceeded" message, print
"-ftemplate-depth-N" rather than "-ftemplate-depth=N".

An unnamed tag type that is declared with a typedef, e.g., 

  typedef struct { int x, y; } Point;

can be used as a template argument. Allow this, and check that we get
sensible pretty-printing for such things.

When pretty-printing an anonymous tag type that is associated with a typedef, use the name of the typedef rather than <anonymous>

to a diagnostic that will be invoked after the diagnostic (if it is
not suppressed). The hooks are allowed to produce additional
diagnostics (typically notes) that provide more information. We should
be able to use this to help diagnostic clients link notes back to the
diagnostic they clarify. Comments welcome; I'll write up documentation
and convert other clients (e.g., overload resolution failures) if
there are no screams of protest.

As the first client of post-diagnostic hooks, we now produce a
template instantiation backtrace when a failure occurs during template
instantiation. There's still more work to do to make this output
pretty, if that's even possible.

asm.  This allows us to properly handle the case when an optimizer duplicates
the asm, such as here:

void bar() {
  int i;
  for (i = 0; i < 3; ++i)
    asm("foo %=" : : "r"(0));
}

we now produce:

_bar:
	xorl	%eax, %eax
	## InlineAsm Start
	foo 0
	## InlineAsm End
	## InlineAsm Start
	foo 1
	## InlineAsm End
	## InlineAsm Start
	foo 2
	## InlineAsm End
	ret

instead of:

_bar:
	xorl	%eax, %eax
	## InlineAsm Start
	foo 1
	## InlineAsm End
	## InlineAsm Start
	foo 1
	## InlineAsm End
	## InlineAsm Start
	foo 1
	## InlineAsm End
	ret

This also fixes a fixme by eliminating a static.

(default: 99). Beyond this limit, produce an error and consider the
current template instantiation a failure.

The stack we're building to track the instantiations will, eventually,
be used to produce instantiation backtraces from diagnostics within
template instantiation. However, we're not quite there yet.

This adds a new Clang driver option -ftemplate-depth=NNN, which should
eventually be generated from the GCC command-line operation
-ftemplate-depth-NNN (note the '-' rather than the '='!). I did not
make the driver changes to do this mapping.

such as replacing 'T' in vector<T>. There are a few aspects to this:

  - Extend TemplateArgument to allow arbitrary expressions (an
    Expr*), and switch ClassTemplateSpecializationType to store
    TemplateArguments rather than it's own type-or-expression
    representation.

  - ClassTemplateSpecializationType can now store dependent types. In
    that case, the canonical type is another
    ClassTemplateSpecializationType (with default template arguments
    expanded) rather than a declaration (we don't build Decls for
    dependent types).

  - Split ActOnClassTemplateId into ActOnClassTemplateId (called from
    the parser) and CheckClassTemplateId (called from
    ActOnClassTemplateId and InstantiateType). They're smart enough to
    handle dependent types, now.
