  -----------
  [clang] Fix elaborated keyword canonicalization.

class and struct keywords are functionally equivalent,
so relying on their equivalence was IFNDR.
This changes it so we treat them as equivalent,
as at least that disallows overloading, which is diagnosable.

This patch also considers a few drive by fixes to preservation
of the presence / abscence of the typename keyword, and improves
a few assertions in that area.

Also improves preservervation of sugar on initializer_list deduction
in order to avoid a few changes in diagnostics.
