Inline this into its only caller.

It's clearer and additionally this gets rid of the usage of `DefmID`,
which doesn't really correspond to anything in the language (it was just
used in the name of this parsing function which parsed a `MultiClassID`
and returned that multiclass's record).

This area of the code still needs a lot of work.
