Finds `cnd_wait`, `cnd_timedwait`, `wait`, `wait_for`, or `wait_until` function calls when the function is not invoked from a loop that checks whether a condition predicate holds or the function has a condition parameter.

    if (condition_predicate) {
        condition.wait(lk);
    }

    if (condition_predicate) {
        if (thrd_success != cnd_wait(&condition, &lock)) {
        }
    }

This check corresponds to the CERT C++ Coding Standard rule CON54-CPP. Wrap functions that can spuriously wake up in a loop. and CERT C Coding Standard rule CON36-C. Wrap functions that can spuriously wake up in a loop.
