[PATCH] Replace PrintStackTrace(FILE*) with PrintStackTrace(raw_ostream&)

[Zachary Turner]

I don't think it matters actually.  The place in CIndex that was using this
was in cindex::Logger::~Logger().  It was using the `stderr' FILE*.  stderr
is unbuffered for one thing, but anwyay as long as we change the rest of
the function to use llvm::errs() then everything should be fine.
