add alternate caching mechanism to allow experimenting for #4747
...
@nunoplopes @aqjune you can experiment by setting ALIVE_OPT to 1 and see if this helps.
A further possible optimization is to persist the "subst" object on the api_context object.
Then in Z3_substitute in api_ast.cpp, instead of declaring locally
expr_safe_replace subst(m);
you can use an attribute on the context to retrieve the same substitution object.
It is not easy to figure out if this matters without having some profiling information so I hope you can determine on your side whether this is useful.
