Eliminate a 'default' case in template argument deduction, where we
were just punting on template argument deduction for a number of type
nodes. Most of them, obviously, didn't matter.

As a consequence of this, make extended vector types (via the
ext_vector_type attribute) actually work properly for several
important cases:
  - If the attribute appears in a type-id (i.e, not attached to a
  typedef), actually build a proper vector type
  - Build ExtVectorType whenever the size is constant; previously, we
  were building DependentSizedExtVectorType when the size was constant
  but the type was dependent, which makes no sense at all.
  - Teach template argument deduction to handle
  ExtVectorType/DependentSizedExtVectorType.
