Loads a 16-byte long value from unaligned memory into a quad vfpu register.

Usage:

ulv.q vd, offset(rm)
{
   vd[0] = *(rm + offset +  0);
   vd[1] = *(rm + offset +  4);
   vd[2] = *(rm + offset +  8);
   vd[3] = *(rm + offset + 12);
}

this is not a real instruction but an alias to output a pair of lvl/lvr instructions.

rm is a general purpose register holding an unaligned memory address. offset is optional.
