The ones in test/experimental/dataflow/[consistency,regression]/test.py was a
copy from test/library-tests/taint/dataflow/test.py.
However, test/library-tests/taint/dataflow/test.py only contains a subset of
test/library-tests/taint/config/test.py, that only contains a subset of
test/library-tests/taint/general/test.py
This commit updates the experimental dataflow tests to be a copy of the
test/library-tests/taint/general/test.py file.
There seems to have been a few changes to the file after it being copied, in
`test_truth` and `test_early_exit`. I have no reproduced those changes.
