This is bug fix for issue 6408. `T[0]` should be always analyzed as "zero
length static array of T", but it was *accidentally* treated as T.init[0].

I can agree that some of proper bug fixes require clear explanation for better
migration. We need to pay attention for them in beta phase, and document them.
