per-pass pools and at least one or two stage-based pools (e.g., front
ends). We may be able to have some implemented for the 4.9 release.
By far the most important aspect of this is defining your pools and
their lifetimes properly. If you're not careful, this will end up like
the old obstack mess we had in the past.
I don't want to discourage the work, but we need to think carefully and
get it right.
