- add -hidir flag to control the destination for .hi files when doing multiple compilations (matches -odir). - change the ml_hi_file component of ModuleLocation from Maybe FilePath to FilePath. We never made use of its Maybeness. - clear out some unused code from the Hsc phase of run_phase and clean up a bit. Fix a bug with the -ohi option at the same time (I don't think it works in 5.xx.x before this patch).
