+ - Refactor Cmm so that it contains only shared stuff\r
+ Add a module MoribundCmm which contains stuff from\r
+ Cmm for old code gen path\r
+\r

+ CmmProcs. Do we still want to do this?\r
+ \r
+ NB: and advantage of continuing to do this is that\r
+ we can do common-proc elimination!\r
+\r
+ - Move to new Cmm rep:\r
+ * Make native CG consume New Cmm; \r
+ * Convert Old Cmm->New Cmm to keep old path alive\r
