+Bound modes class. Used to represent values of pointer bounds.

This is a catchall mode class for modes which don't fit into the above
So why are bounds distinct modes? Is there some inherent reason why
bounds are something other than an integer mode (MODE_INT)?
Similarly what's the rationale behind having new types for bounds? Is
there some reason why they couldn't be implemented with one of the
existing types?
ISTM the entire patch is gated on being able to answer those two questions.
