(DRIVER_SELF_SPECS): Use UNSUPPORTED_ATOMIC_OPTIONS and UNSUPPORTED_HARD_ATOMIC_CPU. * config/sh/sync.md: Update description comments. (I12): New mode iterator. (fetchop_predicate, fetchop_constraint): New code attributes. (atomic_compare_and_swapsi_hard, atomic_compare_and_swap<mode>_hard, atomic_exchangesi_hard, atomic_exchange<mode>_hard, atomic_fetch_<fetchop_name>si_hard, atomic_fetch_<fetchop_name><mode>_hard, atomic_fetch_nandsi_hard, atomic_fetch_nand<mode>_hard, atomic_<fetchop_name>_fetchsi_hard, atomic_<fetchop_name>_fetch<mode>_hard, atomic_nand_fetchsi_hard, atomic_nand_fetch<mode>_hard, atomic_test_and_set_hard): New insns.

(atomic_compare_and_swap<mode>, atomic_exchange<mode>, atomic_fetch_<fetchop_name><mode>, atomic_<fetchop_name>_fetch<mode>, atomic_test_and_set): Integrate new *_hard insns into expanders. * config/sh/sh.opt (mhard-atomic): New option. * doc/invoke.texi (SH Options): Document it.
