This stops most of the post-regalloc passes to be run if the target
doesn't want register allocation. I'd previously moved them all out of
postreload to the toplevel, but Jakub (I think) pointed out that the
idea is not to run them to avoid crashes if reload fails e.g. for an
invalid asm. So I've made a new container pass.
A later patch will make thread_prologue_and_epilogue_insns callable from
the backend.
