gem5/tests/pyunit/util/pyunit_convert_check.py
Bobby R. Bruce f327559ca4 tests,stdlib,python: Add tests for base 10 to 2 SI unit check 
**Note**: Erin needs to complete the commit by expanding this test to
properly test the behavior of this change.

To run the pyunit tests:

```sh
scons build/ALL/gem5.opt -j`nproc`
./build/ALL/gem5.opt tests/run_pyunit.py
```
