Careful.  The ABI is written in inordinately ia64 specific language.
*Why* does it want a 64-bit type?  Does it really want a pointer type,
but is trying to hack around ia64 ilp32 lossage?

I know this definition will fail on c4x, where this would be a
256-bit object.  It will also fail on the tiny ports that define
long long as a 32-bit quantity.

I'm absolutely certain that we should not incorporate such a thing
into our abi without thinking about this.
