Hi,

I was wondering if we should deprecate Dune::AlignmentOf<T> in
dune/common/alignment.hh: it is identical to std::alignment_of<T>, the
fallback implementation was already removed. In addition there's also
the alignof() operator which provides an even shorter version.

I'm not sure which compiler versions introduced the alignof()
operator. Do we have an easy way to find out if it is present in all
supported compiler version? If it is, I suggest to use alignof(T) as the
replacement, otherwise we have to use std::alignment_of<T>::value.
