[DAG] Bound loop dependence check in merge optimization.
The loop dependence check looks for dependencies between store merge
candidates not captured by the chain sub-DAG doing a check of
predecessors which may be very large. Conservatively bound number of
nodes checked for compilation time. (Resolves PR34326).
Landing on behalf of Nirav Dave to unblock the 5.0.0 release.
