commit 46a772f8efb7aa9d350227e8fd5d5809757c3f1e

    Run the complete backend (Stg -> .S) incrementally on each StgBinding
    
    This is so that we can process the Stg code in constant space.  Before
    we were generating all the C-- up front, leading to a large space
    leak.
    
    I haven't converted the LLVM or C back ends to the incremental scheme,
    but it's not hard to do.
