The current handleMoveIntoBundle implementation is unusable,
it attempts to access the slot indexes of bundled instructions.
It also leaves bundled instructions with slot indexes assigned.

Replace handleMoveIntoBundle this with a more explicit
handleMoveIntoNewBundle function which recalculates the live
intervals for all instructions moved into a newly formed bundle,
and removes slot indexes from these instructions.
