  Log Message:
  -----------
  [Codegen] Add a separate stack ID for scalable predicates

This splits out "ScalablePredVector" from the "ScalableVector" StackID
this is primarily to allow easy differentiation between vectors and
predicates (without inspecting instructions).

This new stack ID is not used in many places yet, but will be used in
a later patch to mark stack slots that are known to contain predicates.
