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 conceptually better since the only thing we want this option to do is
   preserve the internal module as constructed by IRgen, before running any
   passes.

 - This also fixes bugs in -disable-llvm-optzns handling with regards to debug
   info.

although in this case we probably just run a risk of duplicating work;
I can't think of how this could cause a bug.

tricks with pointers, we need to make certain we're always using the same 
pointers for things.

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.

This is a pretty minimal test case;  I'll make a better one later.

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

t.m:10:17: warning: incompatible pointer types initializing 'char [4]', expected 'NSString *'
  NSString *a = "Foo";
                ^~~~~
                @
t.m:11:5: warning: incompatible pointer types passing 'char [4]', expected 'NSString *'
  g("Foo");

If a function with a default argument is redefined and the new function also has a defualt argument then add a fixit hint that removes the default argument. Fixes PR5444.
