Add SlotIndexes::repairIndexesInRange(), which repairs SlotIndexes after adding
and removing instructions. The implementation seems more complicated than it
needs to be, but I couldn't find something simpler that dealt with all of the
corner cases.
Also add a call to repairIndexesInRange() from repairIntervalsInRange().
