We cannot (easily) do this. These tests designed to work with `convert-vector-to-llvm` pass which includes some preparations patterns running through `applyPatternsGreedily`.
Also, this pass includes armNeon/armSVE/amx/x86Vector specific transforms (which should probably be handled through their own dedicated `ToLLVMDialectInterface`s).

Motivation for this one is to unhardcode conversion from GPUtoROCDL/NVVM passes https://github.com/llvm/llvm-project/blob/main/mlir/lib/Conversion/GPUToROCDL/LowerGpuOpsToROCDLOps.cpp#L296
