The standard says that alignof(T&) == alignof(T), but - unless we can think 
of examples in which we (1) genuinely need to use alignment_of on a 
reference type and (2) have it return the alignment of the referent and not 
the one of the reference itself - I suggest we just prohibit references.

We'll probably have to prohibit abstract types, too. The standard says that 
they are allowed as well. So we have to tighten our requirements either way, 
and I think it makes sense to constrain ourselves to what we actually use.
