compiler: eliminate jumps to following instruction.
* share/txr/stdlib/optimize.tl (basic-blocks elim-next-jump):
New method, which detects that the basic block ends with a
(jmp label), where label is the next block in emit order.
This jmp instruction can be eliminated.
(basic-blocks elim-dead-code): Walk the reachable labels,
and call elim-next-jmp to remove useless jumps.
