A Size is a combination of width and class
</p><p>TODO: Rename this to <a href="Format.html">Format</a> instead of <a href="Size.html">Size</a> to reflect
the fact that it represents floating point vs integer.
</p><p>TODO: Signed vs unsigned?
</p><p>TODO: This module is currenly shared by all architectures because
NCGMonad need to know about it to make a VReg. It would be better
to have architecture specific formats, and do the overloading
properly. eg SPARC doesn't care about FF80.
