Because you must have BIGGEST_ALIGNMENT <= STACK_BOUNDARY (or 
PREFERRED_STACK_BOUNDARY) in order to be able to allocate objects with 
BIGGEST_ALIGNMENT on the stack.  Otherwise the offsets are not sufficiently 
rounded, even if the stack register is aligned on BIGGEST_ALIGNMENT on 
function entry.
