[NFC][VPlan] Add initial tests for future VPlan-based stride MV

I tried to include both the features that current
LoopAccessAnalysis-based transformation supports (e.g., trunc/sext of
stride) but also cases where the current implementation behaves poorly,
e.g., https://godbolt.org/z/h31c3zKxK; as well as some other potentially
interesting scenarios I could imagine.

The are two test files with the same content. One is for VPlan dump change of
the future transformation alone (I'll update `-vplan-print-after` in the next
PR), another is for the full vectorizer pipeline. The latter have two `RUN:`
lines:
 * No multiversioning, so the next PR diff can show the transformation itself
 * Stride multiversionin performed in LAA, so that we can compare future
   VPlan-based transformation vs old behavior.
