  [clang] simplify placeholder type deduction for constant template parameters

This makes the deduction for dependent types operate in more similar ways
to the non-dependent one, such as when matching template template parameters,
making errors in those generate similar diagnostics to the non-dependent ones.
This also removes some superfluous implicit casts, simplifying the resulting
AST a little bit.
