Merge branch '4.7' of scm.dev.nokia.troll.no:qt/oslo-staging-1 into 4.7-integration

* '4.7' of scm.dev.nokia.troll.no:qt/oslo-staging-1: (50 commits)
  Add the missing license headers to the QString benchmark data
  Fix building of qsimd.cpp on Windows CE
  Use QElapsedTimer for the benchlib tests.
  Properly implement the CPU feature disabling in qsimd.cpp.
  Report the detected CPU features in the corelib boilerplate
  Detect CPU features on ARM by reading the ELF auxvec.
  Split the CPU-detection code into multiple functions for readability
  Fixed delivering gestures to a toplevel widget.
  Unroll the SSSE3 code even more to avoid the need to keep an extra variable for inverting the result
  Don't try to compile the SSE2 and SSSE3 code with compilers that don't support them (e.g. ARM)
  Improve on the SSSE3 with alternate aligning function.
  Add the beginnings of a new SSSE3-based aligning algorithm
  Small fixup
  Update the SSSE3-with-alignment function to use aligned loads.
  Add an ucstrncmp that uses SSSE3 with aligning.
  Add an SSSE3 version of ucstrncmp
  Optimise the tail comparison of ucstrncmp
  Add a version of ucstrncmp with SSE2 with aligning.
  Add an SSE2-optimised version of ucstrncmp
  Add the ucstrncmp benchmarks
