Actually record arrays in classpath.
With https://android-review.googlesource.com/#/c/316151/,
I was under the wrong impression arrays all have the same
access flags. They actually have the visibility of the inner
most component type.
Therefore, we still need to record visibility of array types whose
innermost component type is in the classpath.
