The call to `registry.insert<spirv::SPIRVDialect>();` is needed so that `mlir-translate` can parse the code containing the SPIR-V target attribute, nothing more; there's no translation happening from SPIR-V to LLVM. If the call is not added, then `mlir-translate` throws an error because `SPIR-V` never gets registered.

The question is, should an empty translation to LLVM should be added to mirror all other * to LLVM translation code structure, or is inlining the call ok? I definitely prefer the second option -one less target.
