Add infrastructure for tracking instantiation lemmas (for proofs, and minimization of --dump-instantiations, qe and synthesis solutions). Eliminate quantified arithmetic variables that only have lower/upper bounds. Cleanup strings preprocess, minor fix for str.replace semantics. Reorder cegqi before fmf. Minor cleanup.
