  -----------
  [VPlan] Return invalid for scalable VF in VPReplicateRecipe::computeCost

Replication is currently not supported for scalable VFs. Make sure
VPReplicateRecipe::computeCost returns an invalid cost early, for
scalable VFs if the recipe is not a single-scalar.

Note that this moves the existing invalid-costs.ll out of the AArch64
subdirectory, as it does not use a target triple.

Fixes https://github.com/llvm/llvm-project/issues/160792.
