[PATCH] Add NamespaceCommentCheck to the Google module.

[Daniel Jasper]

Hm.. Should we just move this to misc-? Doesn't seem to be specific to either Google or LLVM style..

Maybe this should contain a string NameSpaceCommentPrefix so that we can configure more and e.g. also support:

  namespace abc {
  } // abc
