[VPlan] Fall back to legacy cost if operands may be force-scalarized. 
If any of the operands of a VPReplicateRecipe have been
force-scalarized, then the legacy cost model skips the scalarization
overhead, but we cannot match this in the VPlan cost model.

Bail out for now in those very rare cases.

Fixes https://github.com/llvm/llvm-project/issues/176720.
