  Log Message:
  -----------
  [VPlan] Account for live-in entries in MinBW used by replicate recipes.

In some cases MinBWs may contain entries for live-ins that are not used
by VPWidenRecipe or VPWidenSelectRecipes. In those cases, the live-ins
won't get processed, so make sure we include them in the count when used
as operands in VPWidenCast and VPWidenSelectRecipe.
