Move codegen tests on old language versions under oldLanguageVersions/

This directory is skipped in JVM IR test generator, so they won't show
up as failed anymore.

Note that only failing tests are moved to oldLanguageVersions/. Tests
which already pass are still being run. It may be useful not to break
them in case we _do_ need to support some pre-1.3 language feature
switches in JVM IR.
