Notes on test changes: - This revealed runtime failures in some tests in pkg/front_end/testcases/inference. Since these tests were never meant to exercise runtime behavior in the first place, I just changed them so that main() does nothing. - This revealed runtime failures in some tests in tests/language_2. These tests began failing because they used "var" for a fields and then later assigned a value to the field that was incompatible with the inferred type. It looks like the intent was for these fields to have type "dynamic", so I changed the tests accordingly.
