Nope. The next round of patches aren't designed to address memory consumption
issues. Sorry.
I'm hoping to solve the remaining issues related to jump threading targets
themselves having PHI nodes, which will give the threader a noteworthy
number of additional jumps it can thread. Any memory savings would come
from things like being able to collect memory for more dead statements
and the like -- secondary effects, and I'd expect them to be small.
