-----------
SelectorQueryCache::add() should not evict cache entries unnecessarily
https://bugs.webkit.org/show_bug.cgi?id=311547
Reviewed by Anne van Kesteren.
Previously, a random cache entry was evicted before checking if the
selector was already cached. This could wastefully evict a valid entry
on cache hit, or even evict the very entry about to be looked up.
Move eviction after ensure() so it only happens when a new entry is
actually inserted.
