Merge remote-tracking branch 'origin/5.6' into 5.7

This change partially reverts 1bfc7f68 about QT_HAS_BUILTIN define and undef in src/corelib/tools/qsimd_p.h. This change is also squashed with "Fall back to c++11 standard compiler flag for host builds" which is done by Peter Seiderer.

     This example illustrates that objects can work together without needing to
     know any information about each other. To enable this, the objects only
