Nikolaj Bjorner 61319ffd85 cache is_shared information in the enode 
observed perf overhead for QF_NIA is that assume_eqs in theory_lra incurs significant overhead when calling is_relevant_and_shared. The call to context::is_shared and the loop checking for beta redexes is a main bottleneck. The bottleneck is avoided by caching the result if is_shared inside the enode. It is invalidated for every merge/unmerge.
