        Place a zero word after each reversed vector table, so that the vtbl
        label is really in the section we would like to claim it is in.  This
        is needed for the GC to work correctly.  Fixes a GHCi segfault

        for yesterday's dummy-word-after-vtbl fix.

        Route all NCG panics to do with missing primop implementations and any
        other panic which could be caused by compiling legitimate sources
        through the function Stix.ncgPrimopMoan.  This emits a helpful message
        explaining what has happened, advises the use of -fvia-C as a
        workaround, and says please mail us.

        Win32 only: implement sane failure semantics + message when out of
        memory, rather than continuing and allowing the rest of the system
        to seg out.  Also, increase the 128M limit to 256M.
        This allegedly fixes the Antony Courtney Win32 segfault.

        Implement a debugging aid: look in GHCi's object symbol tables for
        symbols within DELTA bytes of the specified address, and show their
        names.  Only compiled with -DDEBUG.  The new fn is called ghci_enquire
        and you can call it from within a gdb session.

      pipeLoop: Handle pipelines that end with ineffective
      final stages (e.g., CPP and/or PP) correctly. i.e.,
      need to copy the outcome of the pipeline into the
      expected output file, since the final stage didn't.

      Custom pre-processor documentation

      Added support for a custom pre-processor pass:
        ghc -F -pgmF/path/to/a/pre/processor ...
      will now run /path/to/a/pre/processor over Haskell
      input sources. It is positioned in the compilation
      pipeline just before the compiler proper, but after
      unlit'ing and CPP'ing. The pre-processor is passed
      the following command-line when invoked:
         /path/to/a/pre/processor orig_input_source_file_path
      			    <other options>
      Additionally options can be fed directly to the
      pre-processor via -optF<option> options.
      The -F option causes the pre-processor to run _iff_ one
      has been specified via -pgmF (there's some redundancy
      here, but I went for this cmd-line interface as it's
      consistent with the general -pgm<Foo> story).
       * hooking in a pre-processor is occasionally useful;
         e.g., cheap&cheerful way to integrate language
         extensions with GHC, compile-time syntax/style
         checking etc.
       * Artfully re-using the CPP phase (by specifying your
         own via -pgmP) doesn't really work as the driver
         really assumes that GNU cpp is what's being invoked
         (and path mangling is also performed on Win32 platforms).
         Additionally, there are cases when you want to be
         able to run CPP _and_ a pre-processor.
       * The alternative of running the pre-processor as a
         separate program in a Makefile (say) doesn't work
         in interpreted mode, and this approach also forces
         you to give up on recompilation checking when in
         batch mode.

      Why should pdfjadetex be in the same directory as Jade? Make the much
      less silly assumption that it's on the PATH.

        Correct an error in the handling of implicit parameters
      Mark Shields discovered a bug in the way that implicit parameters
      are dealt with by the type checker.  It's all a bit subtle, and
      is extensively documented in TcSimplify.lhs.
      This commit makes the code both simpler and more correct.  It subtly
      changes the way in which type signatures are treated, but not in a way
      anyone would notice: see notes with "Question 2: type signatures"
      in TcSimplify.lhs.

      follow-on from prev. commit; more tidyups

      - Pet peeve removal / code tidyup, replaced various sub-optimal
        uses of 'length' with something a bit better, i.e., replaced
        the following patterns
         *  length as `cmpOp` length bs
         *  length as `cmpOp` val   -- incl. uses where val == 1 and val == 0
         *  {take,drop,splitAt} (length as) bs
         *  length [ () | pat <- as ]
        with uses of misc Util functions.
        I'd be surprised if there's a noticeable reduction in running
        times as a result of these changes, but every little bit helps.
        [ The changes have been tested wrt testsuite/ - I'm seeing a couple
          of unexpected breakages coming from CorePrep, but I'm currently
          assuming that these are due to other recent changes. ]
      - compMan/CompManager.lhs: restored 4.08 compilability + some code
      None of these changes are HEADworthy.
