There's only one runtime call for your case. and args will be { descriptor_1,
x, descriptor_2 }, where descriptor_1 will be { { 1, 2, 80 }, { 1, 2, 20 }, {
0, 2, 4 } }, descriptor_2 will be { { 1, 5, 16 }, { 0, 2, 4 } }. There's
analysis in Sema that detecting if the item is non-contiguous or not and
codegen only generate descriptor for non-contiguous item.
