Detailed Description

Concrete subclass of svalue: decorate another svalue,
so that the resulting svalue can be identified as being
"interesting to control flow".
For example, consider the return value from setjmp.  We
don't want to merge states in which the result is 0 with
those in which the result is non-zero.  By using an
unmergeable_svalue for the result, we can inhibit such merges
and have separate exploded nodes for those states, keeping
the first and second returns from setjmp distinct in the exploded
graph.
