Skip profiling if the dex file is fully compiled

The OatFile does not store the original dex location that was used to
compile the file. So in order to get the oat file for a given code path
we need to iterate over the inner oat dex files and check against them.

Also, we used to pass the unfiltered code_paths set to the saver which
would make the filtering useless. This fixes the parameter passing as
well.
