fschneider@google.com ac0dd6c295 Add a backward instruction iterator and use it in the liveness analysis.
This avoids the complication when collecting the initial live_in sets while iterating forward.

Also simplify the ForwardInstructionIterator class because we have Goto instructions now and
the last instruction of each block does not use the next-link to
indicate a fall-through anymore.
