bpo-36044: Reduce number of unit tests run for PGO build (GH-14702) Reduce the number of unit tests run for the PGO generation task. This speeds up the task by a factor of about 15x. Running the full unit test suite is slow. This change may result in a slightly less optimized build since not as many code branches will be executed. If you are willing to wait for the much slower build, the old behavior can be restored using './configure [..] PROFILE_TASK="-m test --pgo-extended"'. We make no guarantees as to which PGO task set produces a faster build. Users who care should run their own relevant benchmarks as results can depend on the environment, workload, and compiler tool chain.

# Set of tests run by default if --pgo is specified. The tests below were
# chosen based on the following criteria: either they exercise a commonly used
# C extension module or type, or they run some relatively typical Python code.
# Long running tests should be avoided because the PGO instrumented executable
# runs slowly.
