true for TARGET_64BIT or !flag_pic.
* config/i386/sync.md (*atomic_compare_and_swap_doubledi_pic): Remove.
(atomic_compare_and_swap_double<mode>): Change operand 2 predicate
to cmpxchg8b_pic_memory_operand. Use DWIH mode iterator.
Add insn constraint. Conditionally emit xchg asm insns.
(atomic_compare_and_swap<mode>): Update calls. Check only
cmpxchg8b_pic_memory_operand in memory address fixup.
(DCASMODE): Remove.
(CASHMODE): Rename from DCASHMODE.
(doublemodesuffix): Update modes.
(regprefix): New mode attribute.
(unspecv) <UNSPECV_CMPXCHG_{1,2,3,4}>: Remove.
<UNSPECV_CMPXCHG>: New constant.
(atomic_compare_and_swap<mode>_1): Rename from
atomic_compare_and_swap_single<mode>. Update calls and
unspec_volatile constants.
(atomic_compare_and_swap<mode>_doubleword): Rename from
atomic_compare_and_swap_double<mode>. Update calls and
unspec_volatile constants.
