Back end changes [CgExpr, ClosureInfo, CoreSat, CoreUtils, ~~~~~~~~~~~~~~~~ CmdLineOpts, HscMain, CoreToStg, StgSyn] * Move CoreTidy and interface-file dumping *before* CoreSat. In this way interface files are not in A-normal form, so they are less bulky, and a bit easier to use as input to the optimiser. So now CoreSat is regarded as a pre-pass to CoreToStg. Since CoreTidy pins on utterly-final IdInfo, CoreSat has to be very careful not to change the arity of any function. * CoreSat uses OrdList instead of lists to collect floating binds This in turn meant I could simplify the FloatingBind type a bit * Greatly simplfy the StgBinderInfo data type. It was gathering far more information than we needed. * Add a flag -fkeep-stg-types, which keeps type abstractions and applications in STG code, for the benefit of code generators that are typed; notably the .NET ILX code generator.
