-- 832be2d52d7695cf72fd70248909791fb8ad1003 by Gennadiy Rozental <rogeeff@google.com>: Migrate some FlagImpl fields to bit fields. To save padding space we are migrating some fields representing bool and enums into bit fields. Eventually we'll use remaining padding space for call_once control flag. No other semantic changes made in this CL. PiperOrigin-RevId: 293878165 -- 09162bba5fd8eddacfd732d46fcfeb33074a259f by Samuel Benzaquen <sbenza@google.com>: Correctly initialize the `length_mod` member. Now that it is a raw enum, the default initialization is not enough. PiperOrigin-RevId: 293827817 -- 842b7b805d75c5ab670c52ccd7368cdeba11853d by Matthew Brown <matthewbr@google.com>: Move str_format_internal::LengthMod from extension.h to parser.h; change to enum PiperOrigin-RevId: 293697274 GitOrigin-RevId: 832be2d52d7695cf72fd70248909791fb8ad1003 Change-Id: I90899519e9480543e22638616fdf31a41e7f75c0
