History
Florian Hahn 505ad03c7d [LV] Remove redundant IV casts using VPlan (NFCI). 
This patch simplifies handling of redundant induction casts, by
removing dead cast instructions after initial VPlan construction.
This has the following benefits:

  1. fixes a crash
     (see @test_optimized_cast_induction_feeding_first_order_recurrence)
  2. Simplifies VPWidenIntOrFpInduction to a single-def recipes
  3. Retires recordVectorLoopValueForInductionCast.
