=> DynFlags
-> Module
-> ModLocation
-> NcgImpl statics instr jumpDest
-> UniqSupply
-> DwarfFiles
-> LabelMap DebugBlock
-> RawCmmDecl	the cmm to generate code for
-> Int	sequence number of this top thing
-> IO (UniqSupply, DwarfFiles, [NatCmmDecl statics instr], [CLabel], Maybe [RegAllocStats statics instr], Maybe [RegAllocStats], LabelMap [UnwindPoint])

Complete native code generation phase for a single top-level chunk of Cmm. Dumping the output of each stage along the way. Global conflict graph and NGC stats
