7368f9f7d3 increase build version, better propagation in euf-egraph, handle assumptions in sat.smt 
- increase build version to 4.12.1. This prepares updated release for MacOs-11 build on x86
- move literal propagation mode in euf-egraph to a callback and traversal of equivalence class. Track antecedent by newest equality instead of root. This makes equality propagation to literals have similar behavior as in legacy solver and appears to result in a speedup (10% fewer conflicts on QF_UF/QG-classification/qg5/iso_icl478.smt2 in preliminary testing)
- fix interaction of pre-processing and assumptions. Pre-processing has to freeze assumption literals so they don't get eliminated. This is similar to dependencies that are already frozen.

b6f8538d20 Update parity lemmas 
p != 0  ==>  odd(r)
... added premise p != 0

parity(p) < k    ==>  r <= 2^(N - k) - 1
... do this also in the other branch
    (otherwise we hit the UNREACHABLE in bench3)

Jakob Rath
26e7d0d35a We need to use expr_ref when storing expressions across add calls 
Without this, bench3 created a constraint 2^parity == x * parity which
should have been 2^parity == x * x_inv.
