Add constraints ensuring that the value of result expression of the builtin function corresponds to the value of the function call.

The constraints are only added when deemed necessary, i.e. when maybe_testing_function() returns true, or when testing function depends on the result of this function. This logic is implemented in add_constraints().

Implements string_builtin_functiont.
