I'm not sure. The remaining parts of the patch depend on each other rather
tightly, so I don't know how much I can still break out. While the patch
is still large, a lot of it is of the form
s/counted_for_groups/chain->counted_for_groups/
and similar.
I'll send a patch first that adds the maybe_fix_stack_asms function which
is pretty self-contained. Maybe I'll also try to separate the change that
creates and deletes caller-save insns on every iteration.
