Add nullptr and size check for opening a mem mapped dex file. The bug has an apk with 0 size classes.dex. When dex2oat tries to open the file for layout, it crashes. This adds checks to ensure that the mem map isn't null and has a sane size before opening it as a dex file. Bug: 35892406 Test: mm test-art-host Change-Id: I5f6b5a1e7bbccf4fe3483b68023d51436eb71805
