[PATCH] D139977: [VPlan] Scalarize VPWidenPointerInductionRecipe.

[Florian Hahn via Phabricator via llvm-commits]

Rebase and updated all tests.

The main issue is that the current version of the patch requires creating a temporary GEP instruction to be used with the newly created VPReplicateRecipe. Re-using the existing GEP doesn't work in all cases. Any suggestions on how to best deal with that would be greatly appreciated.
