re PR middle-end/52177 (ICE: verify_gimple failed: non-trivial conversion at assignment with __atomic_is_lock_free())
PR middle-end/52177
* builtins.c (fold_builtin_atomic_always_lock_free,
expand_builtin_atomic_always_lock_free,
fold_builtin_atomic_is_lock_free,
expand_builtin_atomic_is_lock_free): Return and/or test
boolean_true_node/boolean_false_node instead of
integer_one_node/integer_zero_node.
* c-c++-common/pr52177.c: New test.
