  Log Message:
  -----------
  [CostModel] Align the cost model for intrinsics for scalable/fixed-width vectors.

Let getIntrinsicInstrCost call getTypeBasedIntrinsicInstrCost for scalable vectors,
similar to how this is done for fixed-width vectors, instead of falling back
on BaseT::getIntrinsicInstrCost().

If the intrinsic cannot be costed (or is not overloaded by the target),
it will return InstructionCost::getInvalid() instead.

  Log Message:
  -----------
  [SVE] Fix LoopVectorizer test scalalable-call.ll

This marks FSIN and other operations to EXPAND for scalable
vectors, so that they are not assumed to be legal by the cost-model.
