Florian Hahn 2b55ef187c [VPlan] Add helper to run VPlan passes, verify after run (NFC). (#123640) ...

Add new runPass helpers to run a VPlan transformation. This makes it
easier to add additional checks/functionality for each transform run. In
this patch, an option is added to run the verifier after each VPlan
transform.

Follow-ups will use the same helper to also support printing VPlans
after each transform.

Note that the verifier at the moment requires there to be a canonical IV
and vector loop region, so the final lowering transforms aren't run via
runPass yet.
