commit e4f6d245031e04bdd12db390298acec0474a1a46 upstream.
Since all the variable reference hist_fields are collected into
hist_data->var_refs[] array, there's no need to go through all the
fields looking for them, or in separate arrays like synth_var_refs[],
which will be going away soon anyway.
This also allows us to get rid of some unnecessary code and functions
currently used for the same purpose.
