PR middle-end/66867
* builtins.c (expand_ifn_atomic_compare_exchange_into_call,
expand_ifn_atomic_compare_exchange): New functions.
* internal-fn.c (expand_ATOMIC_COMPARE_EXCHANGE): New function.
* tree.h (build_call_expr_internal_loc): Rename to ...
(build_call_expr_internal_loc_array): ... this. Fix up type of
last argument.
* internal-fn.def (ATOMIC_COMPARE_EXCHANGE): New internal fn.
* predict.c (expr_expected_value_1): Handle IMAGPART_EXPR of
ATOMIC_COMPARE_EXCHANGE result.
* builtins.h (expand_ifn_atomic_compare_exchange): New prototype.
* gimple-fold.h (optimize_atomic_compare_exchange_p,
fold_builtin_atomic_compare_exchange): New prototypes.
* gimple-fold.c (optimize_atomic_compare_exchange_p,
fold_builtin_atomic_compare_exchange): New functions..
* tree-ssa.c (execute_update_addresses_taken): If
optimize_atomic_compare_exchange_p, ignore &var in 2nd argument
of call when finding addressable vars, and if such var becomes
non-addressable, call fold_builtin_atomic_compare_exchange.
