RISC-V: Let non-atomic targets use optimized amo loads/stores
Non-atomic targets are currently prevented from using the optimized fencing for
seq_cst load/seq_cst store. This patch removes that constraint.
gcc/ChangeLog:
* config/riscv/sync-rvwmo.md (atomic_load_rvwmo<mode>): Remove
TARGET_ATOMIC constraint
(atomic_store_rvwmo<mode>): Ditto.
* config/riscv/sync-ztso.md (atomic_load_ztso<mode>): Ditto.
(atomic_store_ztso<mode>): Ditto.
* config/riscv/sync.md (atomic_load<mode>): Ditto.
(atomic_store<mode>): Ditto.
