__attribute__((ext_vector_type(4)))' but the argument has type 'float2' (vector
of 2 'float' values)}}
}

Can we add this explicitly to the test just for a record? I guess the warning
message can't be changed to print the type correctly?
Also would it make sense to test other builtin types: double, char...?
