Reviewed by Darin Adler.
Avoid calling collectMatchingRulesForList() when rules is null or empty.
This is done by making collectMatchingRulesForList() inline and having
to the checks before calling a non-inline collectMatchingRulesForListSlow()
function. This allows us to avoid calling collectMatchingRulesForListSlow()
over 60% of the time on Speedometer 3 and results in a 0.20-0.26%
progression overall.
