RFR: 8253177: outputStream not declared in markWord.hpp

[Thomas Schatzl]

Hi all,

  can I have reviews for this trivial change that adds outputStream declaration(s) to the markWord files? Apparently they
  have been missing forever, and in some last-minute testing about some unrelated change the ARM compilers complained
  about it.

Testing: local compilation, tier1

Thanks,
  Thomas
