Factor out common code in PrintState.

Browse source 
The AST and HIR versions of `State::print_ident` are textually
identical, but the types differ slightly. This commit factors out the
common code they both have by replacing `print_ident` with `ann_post`,
which is a smaller function that still captures the type difference.
