[m-dev.] for review: MLDS back-end: implement typeclasses

[Fergus Henderson]

I accidentally left out one of the files in my previous diff.
Here it is.  Anyway, I'll go ahead and commit all these changes now.

----------

runtime/mercury.h:
        Add a typedef for `MR_BaseTypeclassInfo', for use by the
        code generated by rtti_to_mlds.m and mlds_to_c.m
        for base_typeclass_infos.

        Also add another work-around declaration of an MR_TypeCtorInfo;
        with this, the browser directory now compiles.
