commit cc481ec8657e0b91e2f8f9a9eeb3f9ee030635ae

    Generate DWARF info section
    
    This is where we actually make GHC emit DWARF code. The info section
    contains all the general meta information bits as well as an entry for
    every block of native code.
    
    Notes:
    
    * We need quite a few new labels in order to properly address starts
      and ends of blocks.
    
    * Thanks to Nathan Howell for taking the iniative to get our own Haskell
      language ID for DWARF!
