    Merge _stub.o files into the main .o file (Fixes #3687 and #706) · 7b0ff179

    Now GHC still generates the _stub.c files, but the object file is
    automatically merged into the main .o file for a module.  This means
    that build systems (including GHC's own) no longer need to worry about
    looking for _stub.o files and including them when linking.
    
    I had to do lots of refactoring in DriverPipeline to make this work;
    now there's a monad to carry around all the information, and
    everything is a lot tidier.
    
    The _stub.c is now created as a temporary file and removed after
    compilation (unless the -keep-tmp-files flag is on).
