perf/x86: Support constraint ranges
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.
