* builtins.c (expand_builtin_sync_operation): Revert last change.
* optabs.c (expand_bool_compare_and_swap): Compare vs old value,
not vs new value.
(expand_compare_and_swap_loop): Likewise.
(expand_sync_operation): Remove fallback from NAND to AND; invert
memory operand when expanding from cmpxchg.
(expand_sync_fetch_operation): Likewise.
* doc/extend.texi (Atomic Builtins): Fix docs for nand and
compare-and-swap.
* config/alpha/alpha.c (alpha_split_atomic_op): Invert memory operand
when implementing NAND. Fix double-add for AFTER.
* config/alpha/sync.md (sync_nand<I48MODE>): Invert memory operand.
(sync_old_nand<I48MODE>, sync_new_nand<I48MODE>): Likewise.
(sync_compare_and_swap<I48MODE>): Fix compare vs zero. Return old
memory value.
(sync_lock_test_and_set<I48MODE>): Remove extra label and last
memory barrier.
* config/i386/sync.md (sync_compare_and_swap<IMODE>): Fix pattern
to return old memory value.
(sync_compare_and_swap_cc<IMODE>): Likewise.
* config/ia64/ia64.c (ia64_dependencies_evaluation_hook): Early
return pre-reload. Don't consider output or anti dependencies.
* config/ia64/sync.md (IMODE): New.
(modesuffix): Add QI and HI.
(memory_barrier): Simplify expansion.
(sync_compare_and_swap<IMODE>): Use IMODE, not I48MODE.
(cmpxchg_acq_<IMODE>): Likewise.
(sync_lock_test_and_set<IMODE>): Likewise.
(sync_lock_release<IMODE>): Likewise.
