Both match the type of another intrinsic parameter of a vector type, but where each element is subdivided to form a vector with more elements of a smaller type.

Subdivide2Argument allows intrinsics such as the following to be defined:

- declare <vscale x 4 x i32> @llvm.something.nxv4i32(<vscale x 8 x i16>)

Subdivide4Argument allows intrinsics such as:

- declare <vscale x 4 x i32> @llvm.something.nxv4i32(<vscale x 16 x i8>)

Tests are included in follow up patches which add intrinsics using these types.
