[mlir][sparse] Moving integration tests that merely use the Python API

[wrengr]

rebasing

[aartbik]

I think we need a little more than just moving the file. Don't we need to set up some dependences to make this work?
Also, we have asan leak detection disabled (for now) for these kinds of tests that use exec engine, with something like

config.environment['ASAN_OPTIONS'] = 'detect_leaks=0'

[aartbik]

In the first time set-up in any build directory, pass the following:

cmake -G Ninja ../llvm \
   -DLLVM_ENABLE_PROJECTS=mlir \
   ....
  -DMLIR_INCLUDE_INTEGRATION_TESTS=ON \
   ...

after that one-time setup, make sure to always test with

cmake --build . --target check-mlir

or for just integration

cmake --build . --target check-mlir-integration

Adding lit.local.cfg

can you please add comments for each section (as we do in the other lit.local.cfg files in Integration) explaining what every part does.

For example

Disable ASAN's leak detection for python OpsDSL tests.

config.environment['ASAN_OPTIONS'] = 'detect_leaks=0'

Only run when python bindings are enabled.

if not config.enable_bindings_python:

config.unsupported = True

1. I am not sure about the last part so a comment would help ;-)

[aartbik]

Oh, my use of "#" clearly gave an undesirable mark up in my comments ;-)

Re the last part ::shrug:: I just copied the file from another place with python tests, as mentioned in the only documentation I could find

I think that was only needed in the mlir test/python context
It seems safe to me to remove here
