-- 3e6352709da9a529e608eabff862a12bfaecb587 by Gennadiy Rozental <rogeeff@google.com>: Replace local copy of FastTypeId with one shared in absl/base/internal. PiperOrigin-RevId: 304181357 -- c89ea428f732226f4dceb508cd6ba3955a1e49e1 by Andy Getzendanner <durandal@google.com>: Typo fix: add a missing colon. PiperOrigin-RevId: 304064210 -- de2ee7a96bdc7193ffcceb6a2fd6bf464955cbe7 by Samuel Benzaquen <sbenza@google.com>: Reduce the overhead of the registration token by using an empty struct instead of bool. PiperOrigin-RevId: 304054311 -- 222f05d24fb1df7e815946543a7dc78847c83f92 by Derek Mauro <dmauro@google.com>: Turn off hashtablez in opensource builds. Hashtablez is an unsupported, internal-only feature for collecting information about hashtable usage and performance. By turning it off in builds where it is unsupported, we get just a little more performance. PiperOrigin-RevId: 304035460 GitOrigin-RevId: 3e6352709da9a529e608eabff862a12bfaecb587 Change-Id: I0bfe9b5df808a7e35c154b39e6c80e68b0da2b70
