What does this mean?  That DOUBLE PRECISION should *claim* two
storage units even if it doesn't use it?

Well, it wouldn't be the first time that we've claimed XFmode
occupied 16 bytes.  I'd feel disturbed about having the front
end force this, rather than the backend.  Unless we can do
everything with data layout:

   struct double_precision {
	long double r __attribute__((aligned(16)));
   };

and then use the struct everywhere we talk to the middle-end.
