  -----------
  [VPlan] Stop outerloop vectorization from vectorizing nonvector intrinsics (#185347)

In outer-loop VPlan, avoid emitting vector intrinsic calls for intrinsics
without a vector form. In VPRecipeBuilder, detect missing vector intrinsic
mapping and emit scalar handling instead of a vector call.

Also fix assertion when `llvm.pseudoprobe` in VPlan's native path is being
treated as a `WIDEN-INTRINSIC`.
