David Green bc52cc0c7b [LV] Collect dead induction truncates
We currently collect the ICmp and Add from an induction variable,
marking them as dead so that vplan values are not created for them. This
extends that to include any single use trunk from the ICmp, which allows
the Add to more readily be removed too.

This can help with costing vplan nodes, as the ICmp and Add are more
reliably removed and are not double-counted.
