Florian Hahn 2d789ff783 [VPlan] Verify and handle FOR legality during header phi creation (NFC). (#191298) ...

Move the logic to validate FOR users and introduce the split directly to
header phi creation. It makes sense to introduce the header phi and the
splice together.

It also means sinking only needs to be done once, instead for each
VPlan.

Depends on https://github.com/llvm/llvm-project/pull/190681.
