I took another look and this is not only a target option. For example, if it is
hlsl, no matter what target it is (spir-v or dxil), vec3 is preserved. I tried
to add a function `TargetInfo::getOptimalVectorNumElements(const
llvm::FixedVectorType *)`, but it can't cover the language related stuff. If we
add an extra argument, like `bool IsHLSL)`, it is too ugly.
