[issue40807] CODEOP: Show warnings once during _maybe_compile

[Cheryl Sabella]

New submission from Cheryl Sabella <cheryl.sabella at gmail.com>:

When calling `codeop._maybe_compile`, `compile` is run three times.  If the code being compiled causes a warning message, the warning is generated each time that `compile` is called, thus (possibly) showing the message three times.


See msg370163 and that issue for context.
