Added "smart" jump & call to HC08 asm, with other small tweaks
Added "smart" jump & call to HC08 asm, with other small tweaks

Smart jump and call compile the shortest instruction possible. I'm not
yet using them - that is, I have converted _no_ code to use them.

While in the asm, I made u8? and s8? work more "normally" - ie, they
consume their argument. And I added an "assert" that aix and ais are
being passed an immed value.
