(keving) Big Bang introduction of CPR Analysis Pass. Note that now -fstrictness only does the strictness analysis phase, it is necessary to follow this with -fworker-wrapper to actually do the required Core transformations. The -O option in the ghc driver script has been modified appropriately. For now, CPR analysis is turned off. To try it, insert a -fcpr_analyse between the -fstrictness and the -fworker-wrapper options. Misc. comments: - The worker flag has been removed from an ID's StrictnessInfo field. Now the worker info is an extra field in the Id's prag info. - We do a nested CPR analysis, but worker-wrapper only looks at the info for the outermost constructor, else laziness can be lost. - Id's CPR Info in traces and interfaces file follows __M - Worker-wrappery transformation now accounts for both strictness and CPR analysis results.
