To be used together with the no_register_allocation hook.
Everything after register allocation is currently in pass_postreload
rather than pass_rest_of_compilation. This seems arbitrary to me, and
for a target that doesn't do register allocation, pass_postreload isn't
run, so the very last few passes (at least reorg and final) need to be
moved up a level.

* passes.def (pass_compute_alignments, pass_duplicate_computed_gotos,
pass_variable_tracking, pass_free_cfg, pass_machine_reorg,
pass_cleanup_barriers, pass_delay_slots,
pass_split_for_shorten_branches, pass_convert_to_eh_region_ranges,
pass_shorten_branches, pass_est_nothrow_function_flags,
pass_dwarf2_frame, pass_final): Move outside of pass_postreload and
into pass_rest_of_compilation.
