Fix to prevent a dex file from being verified multiple times.

Instead of verifying a dex file whenever one is initialized, they're now
verified when not opened from memory. Also, the way dalvik_system_DexFile
opens dex files has been changed to check for an existing oat file and
get the corresponding dex file from there instead.
