This supports both built-in vector types and the SIMDX<T> Swift types that are used through type aliases like float3. These SIMD types are passed via compatibility structs (with their valued memcpy-d into the ABI compatible struct) as they have special ABI rules. E.g., a float3 is not passed as float3, but as float4 on the ABI level. Previously, we did not expose simd types from Swift to C++ (unless the SIMD types were impoted from clang). rdar://153218744
