Temporally-dependent clauses in complex expressions take exponential time to compile #889

If an expression containing a temporally-dependent clause like @Timestamp > now() - 7d also contains a large number of conjunctive terms a and b and c and d then the analysis/compilation time for the expression takes exponential time. Once there are more than 10 or so terms in the expression this leads to execution timeouts.
