In HLSL we really want to be using the HLSL vector template and other built-in sugared spellings for some builtin types. This updates the type printer to take an option to use HLSL type spellings. This changes printing vector type names from: ``` T __attribute__((ext_vector_type(N))) ``` To: ``` vector<T, N> ```
