This is an experimental address space for strided buffers. These buffers can have structs as elements and a stride > 1. These pointers allow the indexed access in units of stride, i.e., they point at `buffer[index * stride]`. Thus, we can use the `idxen` modifier for buffer loads. We assign address space 9 to 192-bit buffer pointers which contain a 128-bit descriptor, a 32-bit offset and a 32-bit index. Essentially, they are fat buffer pointers with an additional 32-bit index.
