This doesn't look familiar to me at all. I can't even recall a time
when cross jumping ran prior to reload.
My memory could well be wrong, but I'm pretty sure that it originally
ran twice, once before reload and once after.
We did run cross-jumping twice -- but they were both after reload -- the
second one was to deal with the code inserted by reg-stack.
