Detailed Description

A structure representing an allocno (allocation entity).  Allocno
represents a pseudo-register in an allocation region.  If
pseudo-register does not live in a region but it lives in the
nested regions, it is represented in the region by special allocno
called *cap*.  There may be more one cap representing the same
pseudo-register in region.  It means that the corresponding
pseudo-register lives in more one non-intersected subregion.
