Fix omissions in support for the "regcollation" type.

The patch that added regcollation doesn't seem to have been too
thorough about supporting it everywhere that other reg* types
are supported.  Fix that.  (The find_expr_references omission
is moderately serious, since it could result in missing expression
dependencies.  The others are less exciting.)

Noted while fixing bug #17483.  Back-patch to v13 where
regcollation was added.
