    • Allow libcalls to be installed for legacy __sync optabs. · cedb4a1a 
      This allows a target which implements the __sync interfaces
in libgcc to continue to use them transparently with the
new __atomic builtins.

It is assumed that these libgcc routines DO NOT use spinlocks.
This is true of all extant libgcc instances.

        OTI_sync_old_add, OTI_sync_old_sub, OTI_sync_old_ior,

        OTI_sync_new_add, OTI_sync_new_sub, OTI_sync_new_ior,
        OTI_sync_new_and, OTI_sync_new_xor, OTI_sync_new_nand): Move and
        rename from the direct_optab_index enum.

        from the optab_table, not the direct_optab_table.

        (struct atomic_op_functions): Update for optab type changes.
        (maybe_emit_op): Likewise.
        (expand_atomic_fetch_op): Use the legacy fetch-op libcalls.
        * builtins.c (fold_builtin_atomic_always_lock_free): Update call
        to can_compare_and_swap_p.

        sync_compare_and_swap_optab, sync_lock_test_and_set_optab regular
        optabs.
