bc3961c87a7e7760c10319a5b0349c279f7ae3ad by Samuel Benzaquen <sbenza@google.com>:
Improve performance of the registry:
- Reduce contention
- Reduce memory usage for each flag by `6*sizeof(void*)`.
- Replace one immortal allocation per-flag with a single one for all the flags
- Slightly improve single-threaded performance by avoiding the std::map indirections.
