It's the sort of ABI decision that's fixed after it's appeared in a 
release (whereas max_align_t is not the sort of thing that gets embedded 
in external ABIs in a way that gets broken when increasing the alignment, 
but something you use when writing your own allocator).  HJ's i386 ABI 
document, version 1.1 is explicit about this ABI choice (and that for 
_Decimal128, etc.), so presumably it's intended to be followed the same by 
other implementations as well.
