This patch adds the assembly/disassembly for the following
predicate-as-counter instructions:

whilelt: While incrementing signed scalar less than scalar
whilele: While incrementing signed scalar less than or equal to scalar
whilegt: While incrementing signed scalar greater than scalar
whilege: While incrementing signed scalar greater than or equal to scalar
whilelo: While incrementing unsigned scalar lower than scalar
whilels: While incrementing unsigned scalar lower or same as scalar
whilehs: While decrementing unsigned scalar higher or same as scalar
whilehi: While decrementing unsigned scalar higher than scalar
