Rename global variables renames unrelated variables outside project

Qt Creator 3.5 at 0780c1d7634d4e7c9314deba14f370d1f2a14ea6 with test project using Qt 5.6 qtbase at 35793cea28c4bd1d6d8fbae884d9ae3c19745c61

• With code like:

  #include <QCoreApplication>
  #include <QMetaType>
  
  const char *dummy[] =   {"bla"};
  
  int main(int argc, char *argv[])
  {
      QCoreApplication a(argc, argv);
      return a.exec();
  }
  

• Right click on "dummy", choose Refactor/Rename
• Briefly wonder that the bottom pane for renaming pops up and inline editing is not possible
• Rename "dummy" to something else
• Compile the project
• Marvel at gazillons of error messages

What happened is parameter "dummy" of qRegisterNormalizedMetaType() at qtbase/src/corelib/kernel/qmetatype.h:1678 got renamed, too.
