Remove free_value_chain
This patch changes value_release_to_mark and fetch_subexp_value to
return a std::vector of value references, rather than relying on the
"next" field that is contained in a struct value. This makes it
simpler to reason about the returned values, and also allows for the
removal of free_value_chain.
