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:
  Don't run the QGL test on systems that does not have GL support.
  Remove an useless assert from comp_func_SourceOver_sse2()
  QScriptEngineAgent: recompile all the function when installing a debugger.
  QScriptDeclarativeObject:  we need to save the current stack pointer.
  QScriptValue::objectId(): do not assert if the value is not a cell
  Implement the composition mode "Plus" with SSE2
  Clean the CompositionFunction tables of drawhelper
