Yes, of course. Any parameter of the vector GEP may be scalar.
GEP that returns vector of pointers should have one or more vector operands. All vector operands should be with the same vector width.
Scalar operand means the splat vector.

We should also support a vector of pointers and a scalar index, I think.
