LOAD_GLOBAL super reports wrong source positions #109195
Description
Bug report
Bug description:
LOAD_GLOBAL super includes the paranthesis of super() in the source positions.
script:

I hope that it is possible to restore the old source positions. I work currently on python 3.12 support for executing, which relies on correct source positions to perform a correct bytecode -> AST mapping.

3.12
