GHC.CmmToAsm.Format

Formats on this architecture A Format is a combination of width and class

TODO: Signed vs unsigned?

TODO: This module is currently 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.
