compiler/generic/array: Invert conditionals for EMIT-ERROR-BREAK changes.
* This is the halfway point for these changes: Fully half of the
backends are on the new version of the interface while half are
still on the old version.
* Instead of having the conditionals list the platforms that
have been updated (a list that can only grow), list the platforms
that have NOT been updated (a list that can be expected to shrink).
