Original commit message:

    [postmortem] add postmortem metadata for symbols

    As discussed in https://github.com/nodejs/llnode/issues/156, we need
    postmortem metadata for Symbols to properly print Symbol property
    names in postmortem debugging tools. Patch suggested by Ben
    Noordhuis
   (https://github.com/nodejs/llnode/issues/156#issuecomment-350467852).
