(atomic_compare_and_swap<mode>, atomic_exchange<mode>, atomic_fetch_<fetchop_name><mode>, atomic_fetch_nand<mode>, atomic_<fetchop_name>_fetch<mode>, atomic_nand_fetch<mode>): Use TARGET_ATOMIC_ANY as condition. Add TARGET_ATOMIC_STRICT check for SH4A case. Handle new TARGET_ATOMIC_SOFT_TCB and TARGET_ATOMIC_SOFT_IMASK cases. (atomic_test_and_set): Handle new TARGET_ATOMIC_SOFT_TCB and TARGET_ATOMIC_SOFT_IMASK cases. (atomic_compare_and_swapsi_hard, atomic_exchangesi_hard, atomic_fetch_<fetchop_name>si_hard, atomic_fetch_nandsi_hard, atomic_<fetchop_name>_fetchsi_hard, atomic_nand_fetchsi_hard): Add TARGET_ATOMIC_STRICT check.
