[3.8] bpo-37707: Exclude expensive unit tests from PGO task (GH-15009) by miss-islington · Pull Request #15024 · python/cpython

@nascheme @miss-islington

Mark some individual tests to skip when --pgo is used.  The tests
marked increase the PGO task time significantly and likely don't
help improve optimization of the final executable.
(cherry picked from commit 52a48e6)
