We should really refactor these pseudo instruction like intrinsics out of `getVectorIntrinsicIDForCall` https://github.com/llvm/llvm-project/blob/d0ddae678e3f634c988542dfbdde1dd0afe66344/llvm/lib/Analysis/VectorUtils.cpp#L233 

In the non native path, these intrinsics are already being filtered out.

To my knowledge, only `LoopVectorizationLegality` depends on these intrinsics.
