[Frontend] Test platform crashes at second run in pytest #113

Related test: mlir/test_platform.py

The first run in pytest succeeds but the second run fails. Probably some issues with file i/o.

The "second pytest run failure" issue is typically caused by errors in previous tests and global variables not being reset. The revamped frontend https://github.com/cornell-zhang/heterocl/pull/473 removes the heavy reliance on context variables and global variable. Closing this thread as mlir/test_platform.py now works.
