Dx defaults to emitting dexfiles without jumbo opcodes.

There's compatibility issues with going back and forth between versions,
and it's best to have dx default to a stable point and allow
optimizations to be controlled by switches. For jumbo opcodes to be
enabled, dx can be given the switch "--target-api=14".
