In addition, handle vectors of p8. Returns the new type.

Cast a buffer resource (an address space 8 pointer) into a 4xi32, which is the form in which the value must be in order to be passed to the low-level representations used for MUBUF/MTBUF intrinsics.

This is a hack, which is needed in order to account for the fact that we can't define a register class for s128 without breaking SelectionDAG.
