This patch adds a new opcde for intersegment branches. I named it

Thanks to Jason Gloudon for hinting me, how to handle this beast.

No, this isn't how we're doing intersegment branches. Plain jump will
work just fine for this, the only thing we'd potentially need is the
address of the routine to jump through, and that only if we're not going
to require sub PMCs for everything. (And, honestly, I am and have been
leaning this way)
IMHO plain jumps do not work:
- How to get out of JIT code?
- How to jump in not yet JItted code
- How to setup new bounds for current code segment?
- How to run a plain jump with CGoto or Prederef?
