Use __atomic_fetch_{add,and,or,sub,xor} instead of
__atomic_{add,and,or,sub,xor}_fetch when we have no interest in the
result of the operation.Reduces unnecessary codegen that provided the result of the atomic operation that was not used. Change brings closer alignment with atomics available in C11 standard and will reduce review effort when they are integrated.
