Subject: [PATCH] py/runtime: mp_raise_msg(): Accept NULL argument for message.
In this case, raise an exception without a message.
This would allow to shove few code bytes comparing to currently used
mp_raise_msg(..., "") pattern. (Actual savings depend on function code
alignment used by a particular platform.)
