Sean Silva 3734f69119 Remove basic_mt from the heavydep tests
This was an aspirational goal at an earlier stage in the project where
the focus was heavily on programs with state, control flow, and
lists/dicts. We will circle back to such programs likely 2022H2 at some
point, but for now, having this test doesn't add much, since basically
nothing works or is being worked on.

Additional end-to-end tests with heavy dependencies (heavydep tests)

Some end-to-end tests require additional dependencies which don't make sense to include as part of the default torch-mlir setup. Additionally, these dependencies often don't work with the same HEAD PyTorch version that torch-mlir builds against at the C++ level.

We have a self-contained script that generates all the needed artifacts from a self-contained virtual environment. It can be used like so:

# Build the virtual environment in the specified directory and generate the
# serialized test artifacts in the other specified directory.
# This command is safe to re-run if you have already built the virtual
# environment and just changed the tests.
build_tools/torchscript_e2e_heavydep_tests/generate_serialized_tests.sh \
  path/to/heavydep_venv \
  path/to/heavydep_serialized_tests

# Add the --serialized-test-dir flag to point at the directory containing the
# serialized tests. All other functionality is the same as the normal invocation
# of torchscript_e2e_test.sh, but the serialized tests will be available.
tools/torchscript_e2e_test.sh --serialized-test-dir=path/to/heavydep_serialized_tests

The tests use the same (pure-Python) test framework as the normal torchscript_e2e_test.sh, but the tests are added in build_tools/torchscript_e2e_heavydep_tests instead of frontends/pytorch/e2e_testing/torchscript.

We rely critically on serialized TorchScript compatibility across PyTorch versions to transport the tests + pure-Python compatibility of the torch API, which has worked well so far.
