This patch series try to improve the SH4 target by using the (more or
less) recently introduced TCG features. It also fixes some issues spot
when writting the patches (linking of TB with different flags, SH4-A
specific instructions allowed on SH4) and correctly trap unaligned
accesses.

v3:
- Use extr instead of extrh/extrl in gen_store_fpr64, as suggested by
  Richard Henderson
- Use cpu_loop_exit_restore instead of cpu_loop_exit/cpu_restore_state
  in superh_cpu_do_unaligned_access
- Add a patch to convert the remaining cpu_loop_exit/cpu_restore_state
  to cpu_loop_exit_restore
- Add Reviewed-by entries

v2:
- Add some comments in the struct DisasContext declaration, as suggested
  by Philippe Mathieu-Daudé
