Do away with that 'ineffective CPP' malarkey. run_phase now returns the FilePath of its output file; in the event CPP isn't required, we then just return the input file. (The extra LINE pragma that the 'ineffective CPP' inserted was a NOP). Appears to speed things up a bit; mingw/Win32 builds no longer need to do a slow copyFile operation - other plats are saved from doing a System.system call. BTW, there's an opportunity to shorten the critical path for .hs files some in the driver: at the moment 'unlit' is run over all input.
