The m_VScale() matcher is unusual in that it requires a DataLayout. It is currently used to determine the size of the GEP type. However, I believe it is sufficient to check for the canonical `<vscale x 1 x i8>` form here -- I don't think there's a need to recognize exotic variations like `<vscale x 1 x i4>` as a vscale constant representation as well.
