[issue2459] speedup for / while / if with better bytecode

Hold off on reviewing this. There's one bug around the peepholer not
turning itself off when line numbers skip by more than 127, and another
around the traceback generator still assuming line numbers are unsigned.
I'll post another patch when those are fixed and tested. I may not get
to it for a day or two, so someone else is welcome to update the patch
instead. :)
