Detailed Description

   The structure contains information about hard registers can be
   assigned to allocnos.  Usually it is allocno profitable hard
   registers but in some cases this set can be a bit different.  Major
   reason of the difference is a requirement to use hard register sets
   that form a tree or a forest (set of trees), i.e. hard register set
   of a node should contain hard register sets of its subnodes.
