[PATCH] Add CommentOptions, allow specifying custom comment block commands

[Ben Gertzfield]

  Got the unit tests working! (I was running gdb on the wrong command.)

  The core problem was that I previously required the comment options when constructing
  CommandTraits -- but in PCH-reading mode, we construct CommandTraits way before reading
  the PCH.

  Now, I added a new method CommandTraits::RegisterCommentOptions() with which we can
  register comment options from LangOptions after parsing the PCH.  Tests are now passing.

    - Don't pass in -fcustom-comment-block command when reading PCH in test.
    - Add CommandTraits::RegisterCommentOptions(). Call from ASTInfoCollector::updated().
