eval: drop passing (critical) as an argument
eval: drop passing (critical) as an argument

There is no point in passing (critical) as an argument when
we alredy rely on a bunch of static variables.  If eval needs to be
reentrant, we should instead have something like "struct eval_state"
and pass a pointer to that as an argument.
