Mark array classes as verification attempted
We now initialize all array classes in the compiler driver. This in
turn will ensure they are marked verified in the image. This
prevents dirty pages in the image since we would otherwise set the
flags in the zygote.
On BusinessCard:
Reduces shared dirty from 636k -> 432k for boot.art, and dirty pages
from 183 to 132.
