The build compare script needs to be updated to handle some new exceptions and tweaking some old so that we have a clean baseline again.

* The special treatment of the lib/classlist file needs to apply in macosx bundle images.
* Since the changes to debug symbols handling, the native comparison on Windows can be greatly simplified by just building an _NT_SYMBOL_PATH that covers all known locations for pdb files in the build output, with no need to unzip any .diz files dynamically. This removes the need for special cases which currently aren't working.
* The sec-bin files on Windows now contain .pdb and .map files, which need to be added to exception list.

We still have non deterministic output from javadoc which makes comparisons fail intermittently. Filing separate issue for that.
