Yeah, but why?  I see no good reason why those fields need to be first.

Looking at it closer, I agree that GUC_EXPLAIN and GUC_RUNTIME_COMPUTED
should be moved to be with the other non-units flags.  But I don't
see why we need to re-order the entries more than that.  I'm concerned
for one thing that the order of the entries in this list stay comparable
to the order in which the flags are dealt with in other code, such as
pg_settings_get_flags or the guc_tables.c entries.
