Introduce a new representation for template template
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.
