I seem to recall that LCC was also used, at least on 10th Ed. Am I
imagining things, or was that real?

I think there are a few Research-specific hacks to add
additional stab info for pi(9.1) and on request insert
basic-block profiling for lcomp(1), but nothing major.
Maybe we did some hacking on c2 as well. I know I did
a lot of c2 cleanup later in my personal hacking in
Toronto, but I don't think I did much if any in New
Jersey. But that's independent of the compiler (modulo,
I think, some of my later fixes discovered by using c2
with a different compiler).
