  [TTI] Handle experimental.vp.reverse in BasicTTIImpl (#147868)

A experimental_vp_reverse isn't exactly functionally the same as
vector_reverse, so previously it wasn't getting picked up by the generic
VP costing code that reuses the non-VP equivalents.

But for costing purposes it's good enough so we can reuse it.

The type-based cost for vector_reverse is still incorrect and should be
fixed in another patch.
