rs6000.c (rs6000_emit_sync): Remove support for operand wrapped in NOT.
* config/rs6000/rs6000.c (rs6000_emit_sync): Remove support for
operand wrapped in NOT. Emit NAND as (ior (not X) (not Y)).
(rs6000_split_atomic_op): Emit NAND as (ior (not X) (not Y)).
* config/rs6000/sync.md (sync_nand<mode>): Represent NAND in RTL.
Call rs6000_emit_sync with CODE=NOT and unmodified operands.
Ignore sub-word case for now.
(sync_nand<mode>_internal): Represent NAND in RTL.
(sync_old_nand<mode): Same.
(sync_old_name<mode>_internal): Same.
(sync_new_nand<mode>): Same.
(sync_new_nand<mode>_internal): Same.
(sync_boolcshort_internal): Expect NAND.
