Merge branch '4.7' of scm.dev.nokia.troll.no:qt/oslo-staging-2 into 4.7-integration

* '4.7' of scm.dev.nokia.troll.no:qt/oslo-staging-2:
  Do check after all if we have partialUpdateSupport.
  QDeclarativeEngineDebugServer: Fix crash when trying to update non-properties.
  Doc: use const& in foreach when applicable.
  QGLBuffer::bind()/release() should not be const functions.
  Use SSSE3 to convert from RGB888 to RGB32
  Extend the build system to SSSE3
  CPU feature detection for x86_64
  Use the appropriate CPUID bitmap for detecting SSE3 etc
  Skip tst_QLineEdit::QTBUG697_paletteCurrentColorGroup on non-x11
  Stabilize tst_qlineedit.cpp
  QScriptEngineAgent:  ensure that the top of the backtrace is correct in exceptionThrow
  Fix QLineEdit's Highlight color when inactive.
