aarch64: Implement TImode compare-and-swap
This pattern will only be used with the __sync functions, because
we do not yet have a bare TImode atomic load.
* config/aarch64/aarch64.c (aarch64_gen_compare_reg): Add support
for NE comparison of TImode values.
(aarch64_emit_load_exclusive): Add support for TImode.
(aarch64_emit_store_exclusive): Likewise.
(aarch64_split_compare_and_swap): Disable strong_zero_p for TImode.
* config/aarch64/atomics.md (@atomic_compare_and_swap<ALLI_TI>):
Change iterator from ALLI to ALLI_TI.
(@atomic_compare_and_swap<JUST_TI>): New.
(@atomic_compare_and_swap<JUST_TI>_lse): New.
(aarch64_load_exclusive_pair): New.
(aarch64_store_exclusive_pair): New.
* config/aarch64/iterators.md (JUST_TI): New.
