Hmm, how would this work? Would we have index AM implementation run
some function that register their support methods somehow at startup?
Hopefully we're not going to have the index AMs become shared libraries.

In any case, if indexes AMs and sequence AMs go this route, that
probably means the column store AM we're working on will probably have
to go the same route too.
