[PATCH] MC: Support larger COFF string tables

[Nico Rieck]

  I've split the base64 encoding into a separate commit now. But even the single-slash encoding would need a 1MB test file to test this change.

  When running locally, making python available in PATH can be easily done by picking the current interpreter path in lit.cfg.
  Is there any chance to skip this test otherwise?

  Adding ddunbar as suggested.
