Detailed Description

An element in an aggegate part of a jump function describing a known value
   at a given offset.  When it is part of a pass-through jump function with
   agg_preserved set or an ancestor jump function with agg_preserved set, all
   unlisted positions are assumed to be preserved but the value can be a type
   node, which means that the particular piece (starting at offset and having
   the size of the type) is clobbered with an unknown value.  When
   agg_preserved is false or the type of the containing jump function is
   different, all unlisted parts are assumed to be unknown and all values must
   fulfill is_gimple_ip_invariant.
