call_function() and do_call_core() functions of Python/ceval.c use C_TRACE() macro to call the profiler, but PyObject_Call() and similar functions like _PyObject_FastCallKeywords() don't. Is it a bug or a deliberate choice for performance? Since PyObject_Call() and similar functions have now fast paths, I don't think that it's still needed to have these fast paths in ceval.c too. But I kept fast paths in ceval.c because of C_TRACE().
