Nikita Popov 777187cbaf Don't use UNREFs during array operations ...

Perform DEREFs instead. We were already doing this in some, but not
all places.

While UNREFs are supposed to be transparent, in practice they have
rare observable side effects. Calling array_merge() on an array
should never change how that array behaves.
