  [LV] Allow re-processing of operands of instrs feeding interleave group

Follow up to d216615518 to update dead interleave group pointer detection
to allow re-processing of operands of instructions determined to only feed
interleave groups.

This is needed because instructions feeding interleave group pointers
can become dead in any order, as per the newly added test case.
