Add a GS_PADDING_IVAR macro. This defines the void *gs_unused; instance variable with __attribute__((unused)) on clang so that the static analyser only reports unused ivars that we expect to be used. This also makes it slightly easier to add the padding ivar to new classes.

Note: The padding ivar has been added to NSRegularExpression.  This will break the ABI for anyone subclassing NSRegularExpression, but hopefully that's no one (done before the next release, to make sure that we don't break the ABI between releases, only for people following -trunk).
