5c7eaec566 #6364 - remove option of redundant clauses from internalization 
gc-ing definitions leads to unsoundness when they are not replayed.
Instead of attempting to replay definitions theory internalization is irredundant by default.
This is also the old solver behavior where TH_LEMMA is essentially never used, but is valid for top-level theory lemmas.
