Move configure --disable-float8-byval to pg_config_manual.h
This build option was once useful to maintain compatibility withversion-0 functions, but those are no longer supported, so this optionis no longer useful for end users. We keep the option available todevelopers in pg_config_manual.h so that it is easy to test thepass-by-reference code paths without having to fire up a 32-bitmachine.Discussion:https://www.postgresql.org/message-id/flat/f3e1e576-2749-bbd7-2d57-3f9dcf75255a@2ndquadrant.com
