<vscale x 1 x *> types aren't legal with Zve32*. The type legalizer is unable to widen non-VP masked load. It currently asserts on a call getVectorNumElements which isn't valid for scalable vectors. Replacing that with getVectorElementCount crashes in legalizing concat_vectors due to the padding of the mask with 0 elements.
I don't think we can do the 0 element padding for scalable vectors. Probably the best thing to do is to widen using VP_LOAD and limit the VL instead of padding the mask.
