7eb14d9d - [TTI] Fix value-based BasicTTIImpl vp.{gather,scatter} costing (#148020)

[TTI] Fix value-based BasicTTIImpl vp.{gather,scatter} costing (#148020) After #147677 we now preserve value based costing for vp intrinsics instead of switching it to type based costing. However for vp.gather and vp.scatter, even though they fallback to their functionally equivalent masked.gather and masked.scatter, the number of arguments are different due to the alignment being a dedicated argument. This caused a crash detected at https://lab.llvm.org/staging/#/builders/210/builds/988 Thix fixes it by explicitly handling the two intrinsics and adding test coverage. Note that the type based costing isn't yet implemented for masked.gather/masked.scatter so it doesn't show up correctly.
