the old builder API.  This percolated a bunch of changes up to the
Checker class (where CheckLocation has been renamed VisitLocation) and
GRExprEngine.  ProgramPoint now has the notion of a "LocationCheck"
point (with PreLoad and PreStore respectively), and a bunch of the old
ProgramPoints that are no longer used have been removed.

parameters. Rather than storing them as either declarations (for the
non-dependent case) or expressions (for the dependent case), we now
(always) store them as TemplateNames. 

The primary change here is to add a new kind of TemplateArgument,
which stores a TemplateName. However, making that change ripples to
every switch on a TemplateArgument's kind, also affecting
TemplateArgumentLocInfo/TemplateArgumentLoc, default template
arguments for template template parameters, type-checking of template
template arguments, etc.

This change is light on testing. It should fix several pre-existing
problems with template template parameters, such as:
  - the inability to use dependent template names as template template
  arguments
  - template template parameter default arguments cannot be
  instantiation

However, there are enough pieces missing that more implementation is
required before we can adequately test template template parameters.

handling template template parameters properly. This refactoring:

  - Parses template template arguments as id-expressions, representing
    the result of the parse as a template name (Action::TemplateTy)
    rather than as an expression (lame!).

  - Represents all parsed template arguments via a new parser-specific
    type, ParsedTemplateArgument, which stores the kind of template
    argument (type, non-type, template) along with all of the source
    information about the template argument. This replaces an ad hoc
    set of 3 vectors (one for a void*, which was either a type or an
    expression; one for a bit telling whether the first was a type or
    an expression; and one for a single source location pointing at
    the template argument).

  - Moves TemplateIdAnnotation into the new Parse/Template.h. It never
    belonged in the Basic library anyway.

This is reasonable because people know what they are doing when they 
intentionally dereference the pointer.
So now we only emit warning when a pointer variable is use literally.

When trying to assign a regular string literal to an Objective-C 'id' type or a pointer to an NSString, emit a code insertion hint that turns it into an Objective-C string. For example:

@class NSString;

@interface Test
+ (void)test:(NSString *)string;
@end

void g(NSString *a);

void f() {
  NSString *a = "Foo";
  g("Foo");
  [Test test:"Foo"];
}

will produce

  NSString *a = "Foo";
