[VPlan] Run initial recipe simplification on VPlan0. (#176828) 
In some cases, LV gets simplifyable IR as input. Directly apply
simplifications on the initial VPlan0 to avoid vectorization in cases
where the loop body can be folded away.

Using the end-to-end pipeline, this is relatively rare, but when
reducing test cases, the reduction often ends up with cases with trivial
folds. Rejecting those will result in more robust & realistic test
cases.

As follow-up, I also plan to add initial dead recipe removal.

Depends on https://github.com/llvm/llvm-project/pull/176795.
