Icelake extended the general counters to 8, even when SMT is enabled. However only a (large) subset of the events can be used on all 8 counters. The events that can or cannot be used on all counters are organized in ranges. A lot of scheduler constraints are required to handle all this. To avoid blowing up the tables add event code ranges to the constraint tables, and a new inline function to match them.
