C++ PATCH for c++/77742 (-Waligned-new and placement new)

It doesn't make sense to warn about placement new of over-aligned types; most occurrences are likely to be doing this in order to provide properly aligned memory by allocating it first and then using the standard non-allocating placement new. Also, the discussion of -Waligned-new on HPPA led me
