@shafik : I'm trying to have libcxx compile with `-Wzero-length-array`. With these two commits, we're done.

@ldionne : I undid the reuse of `__padding`. The motivation is two folds: 1st it would create an extra header dependency (moving `__padding` definition to another header so that it can be included both in `string` and `compressed_pair.h`) and second  `compressed_pair` is now scarcely used, so it's probably ok to keep related stuff in the same header (?).
