The next steps from here would be:
o Figure out how to deal with the GTY param_is attribute.
o Replace all ggc_alloc calls with a use of the proper define,
so that we know the type code for everything we allocate with
the GC alloctors.
o Hack gengtype some more to write out an array of marker
functions that can be called by typecode index.
o Implement better GC strategies?
This was bootstrapped just to make sure it works. Before going on to
the next step, I'd like to hear from people what they think of this
approach.
