limit symbols exported when using --enable-mergelibs
when doing LTO and --enable-mergelibs, we can improve the effectiveness
of LTO by marking more code as internal to the merged library.
So introduce a new macro UNLESS_MERGELIBS, which we can wrap around
*_DLLPUBLIC annotations
Also introduced here is a script that can be run on a completed build to
determine which classes can be marked with this macro.
