#10971: Translate functions when no locale are expensive no-ops

 When there is no locale loaded WordPress creates a new empty Translations
 object on every call to any translation function (__(), ...) which is then
 used to do the fruitless no-op lookup.

 Reverting to the 2.7 style (of testing $l10n[$domain] directly in
 translate() and friends) makes page load of new install of 2.9 trunk front
 page 17% faster!!
