ART: Add very-large threshold to dex2oat
Add a variable threshold to dex2oat. If the total dex file size for
an app reaches this threshold, dex2oat will punt all compilation and
compile the app with verify-at-runtime. This ensures smaller compile
time and memory thrashing, while still extracting the dex files and
thus helping with dirty memory later.
Added tests.
