Given a canonical value C as a starting point, create an
inference context that contains each of the bound values
within instantiated as a fresh variable. The f closure is
invoked with the new infcx, along with the instantiated value
V and a instantiation S. This instantiation S maps from
the bound values in C to their instantiated values in V
(in other words, S(C) = V).
