Fix mismanaged dyn_env variable.
* eval.c (bindings_helper): In the parallel binding case, only allocate
a new dynamic env when it is needed (because a special variable is
being bound), rather than unconditionally.
Consequently, only modify dyn_env when the dynamic environment actually
needs to be extended. Constructs that use bindings_helper are only
wrapped in the dynamic environment save/restore form
sys:with-saved-vars if they bind special variables.
