Re: [PATCH] Your new friend and mine, gensimplify

Except, in order to preform tree simplification as well, I had to
significantly  duplicate most of the output routines (since they don't
defer output, i can't just do btoh at once, and the tree output routines
are already starting to diverge, so it made sense).

It also required code from genemit, which has now been modified as well.

In other words, i'd really have to mess up genrecog something awful to do
this, because genrecog only does stuff for rtx,and it never will do stuff
for trees (since it's whole purpose is to generate routinse that operate
on rtx), nor should it.

It was a first pass, and rather than start from scratch, i stared with a
a merged genrecog and genemit.
