At present, after reload. We'd need to teach reload to
create conditional spills before we could move it earlier.
I suspect it'll never go further back than just before sched1,
as too few optimization passes would be able to do anything
useful with it.

I would expect not, but did make provision for it in the bits
that scan for stores.
