This is not what this set of changes is doing.  These are the
mechanical side-effects of the new hash table design.  We are not
going to start re-writing the whole compiler by ourselves.  We have
set out to make very specific API changes and we are hoping that other
maintainers will start contributing in their own areas.

Easier to use hash tables make code easier to maintain and understand.
