[SYSTEMDS-2652] Fix function deep copy for eval fcalls (for predicates)

This patch fixes an issue of the deep copy of FOR statement blocks if
eval requires to keep the unoptimized functions. Before we introduced
eval, this deep copy was only used for uncontended recompilation in
parfor and thus, predicate hops (from, to, increment) were only copied
if necessary. However, this is invalid for the creation of unoptimized
functions from which otherwise no valid execution plans can be compiled.
This led to missing predicate variables because the predicate
instructions were missing.
