    Some PGO tests are failing when Python is build with options ./configure --disable-test-modules --enable-optimizations . Test failures are caused by missing _testcapi module.

    ./python -m test --pgo --timeout=1200 || true
    test test_array failed
    test test_bytes failed
    test test_cmath failed
    test test_codecs failed
    0:00:23 load avg: 1.98 [13/44] test_datetime
    Failed to call load_tests:
    ...
    ModuleNotFoundError: No module named '_testcapi'
    test test_embed failed
    test test_float failed
    test test_itertools failed
    test test_ordered_dict failed
    test test_pickle failed
    test test_struct failed
    test test_unicode failed
    test test_xml_etree_c failed

    bpo-46906: Add PyFloat_Pack8() to the C API (GH-31657)
    882d809 
    Add new functions to pack and unpack C double (serialize and
deserialize):

* PyFloat_Pack2(), PyFloat_Pack4(), PyFloat_Pack8()
* PyFloat_Unpack2(), PyFloat_Unpack4(), PyFloat_Unpack8()

Document these functions and add unit tests.

Rename private functions and move them from the internal C API
to the public C API:

* _PyFloat_Pack2() => PyFloat_Pack2()
* _PyFloat_Pack4() => PyFloat_Pack4()
* _PyFloat_Pack8() => PyFloat_Pack8()
* _PyFloat_Unpack2() => PyFloat_Unpack2()
* _PyFloat_Unpack4() => PyFloat_Unpack4()
* _PyFloat_Unpack8() => PyFloat_Unpack8()

Replace the "unsigned char*" type with "char*" which is more common
and easy to use.
