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.

Correctly initialize the `length_mod` member.
Now that it is a raw enum, the default initialization is not enough.
