First round of size reduction for JumpTargets.  Reduce their size by

LGTM.

Now that the BreakTarget subclass doesn't need to have a code generator or macro
assembler, its constructor could call the JumpTarget constructor.

I don't think that will make a difference since the JumpTarget default
constructor sets the direction to FORWARD_ONLY anyway.
