Size

Description

Sizes on this architecture A Size is a combination of width and class

TODO: Rename this to Format instead of Size to reflect the fact that it represents floating point vs integer.

TODO: Signed vs unsigned?

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.
