Certain collators and subject strings may take this new fast path without calling into the (slow) ICU comparison functions. This CL can be roughly split into three topics: 1. The fast path check, precomputed and implemented as a whitelist on the current locale string. 2. The actual fast path, which checks subject string eligibility and performs L1 and L3 collation weight comparisons all in one pass. 3. Resuming from an aborted fast-path into the generic path. A longer overview is available at https://docs.google.com/document/d/1oyDwjYn2JyHsx2YnJJKhjX0WMNQXb8ao86-DRzqiYNg/edit?usp=sharing JetStream2/cdjs scores improve by roughly 40%.
