Marc Mutz a54d44298f QLatin1String: Fix UB (nullptr passed) in relational operators
Found by UBSan:

  qstring.h:1160:44: runtime error: null pointer passed as argument 1, which is declared to never be null
  qstring.h:1160:44: runtime error: null pointer passed as argument 2, which is declared to never be null

Fix by avoiding the memcmp() calls if there's a chance that they
might be called with nullptr.

While at it, also implement !=, >, <=, >= in terms of ==, <,
and add a test, because this particular UB was not fingered by
any of the QtCore test cases, but by a Qt3D one.

This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.

Linux X11:

   * The user must be logged in to an active desktop; you can't run the
     autotests without a valid DISPLAY that allows X11 connections.

   * The tests are run against a KDE3 or KDE4 desktop.

   * Window manager uses "click to focus", and not "focus follows mouse". Many
     tests move the mouse cursor around and expect this to not affect focus
     and activation.

   * Disable "click to activate", i.e., when a window is opened, the window
     manager should automatically activate it (give it input focus) and not
     wait for the user to click the window.
