	I think it more likely is a latent bug in the scheduler, not a
problem with the patterns.  Admittedly the volatile load-locked insn does
not appear until the post-reload splitter after sched1, but it still seems
that the scheduler should not move volatile mem.

	What happens on Alpha?  I would expect that it would show similar
symptoms.
