Clock gating checks

WebClock gating checks are inferred for the two AND gates, but not for the OR gate. This is because although both CLK1 and CLK2 arrive at the OR gate, both are consumed as clocks downstream. PrimeTime therefore understands that both of these are clock signals being steered and combined with logic, and no gating check is inferred.
