cpython-lru_cache-weakref: Python/import.c annotate

annotate Python/import.c @ 37468:04afb3650847 legacy-trunk

Generate line number table entries for except handlers. Re-enable all the tests in test_trace.py except one. Still not sure that these tests test what they used to test, but they pass. One failing test seems to be caused by undocumented line number table behavior in Python 2.4.
