The test is already there (use of `opt -passes="<pass-name>"` in test line is enough)

There is a misleading PR name: NewPM initial registration was done in https://github.com/llvm/llvm-project/pull/188285, but this wrapper was kinda fake, it instantiated the full ModulePass (`class SPIRVEmitIntrinsics : public ModulePass, InstVisitor<...>`) just to call runOnModule() directly (NewPM logic), skipping PassManager entirely

I have corrected the PR title
