    Add HeapView functionality
    
    This pulls parts of Joachim Breitner's ghc-heap-view library inside GHC.
    The bits added are the C hooks into the RTS and a basic Haskell wrapper
    to these C hooks. The main reason for these to be added to GHC proper
    is that the code needs to be kept in sync with the closure types
    defined by the RTS. It is expected that the version of HeapView shipped
    with GHC will always work with that version of GHC and that extra
    functionality can be layered on top with a library like ghc-heap-view
    distributed via Hackage.
    
    Test Plan: validate
