Portable dumper ideas

Wouldn't we get a tremendous performance boost by having the
lrecord_implementations_table indices be constant? We would lose a
level of indirection on every FOOP, because it would not have to
examine lrecord_implementations_table itself.
Yes, this is a great idea. I think the reason the changeover to
minimal tagbits was a wash speedwise was because of increased
time spent type checking. We got rid of the pointer masking and
unmasking, but almost all the type checks got more expensive.
