[issue34247] PYTHONOPTIMZE ignored in 3.7.0 when using custom launcher

This seems closely related to the work Victor is already pursuing to resolve bpo-34170 for Python 3.8 (e.g. https://github.com/python/cpython/commit/56b29b6d6fa3eb32bb1533ee3f21b1e7135648a0 ).

The bpo-34170 changes are more invasive than we'd like for a maintenance release, but it would be preferable to keep at least any new Python 3.7 test cases somewhat aligned with their Python 3.8 counterparts.
