I tested with this setting and it works fine with -XX:+SegmentedCodeCache because the code for segmented code cache only checks Arguments::is_interpreter_only().  This doesn't seem right to me, but the testing also expects this to work.  I could fix the tests to not do this. Now I don't know what anyone wants!
