ec5b1bdfa3 opencl: Fix type of parameter for clGetContextInfo 
CL_CONTEXT_NUM_DEVICES expects a cl_uint.

Passing size_t results in a wrong value for numDevices on hosts where
sizeof(cl_uint) != sizeof(size_t). This results in errors like these:

  Tesseract Open Source OCR Engine v3.05.00dev with Leptonica
  OpenCL error code is -44 at   when clCreateKernel kernel_HistogramRectAllChannels .
  OpenCL error code is -44 at   when clCreateKernel kernel_HistogramRectAllChannelsReduction .
  OpenCL error code is -48 at   when clSetKernelArg imageBuffer .

94be4be4be ccutil/ambigs: Optimize tesseract::UnicharIdArrayUtils::compare 
The compare method is called very often, so even small improvements
are important.

The new code avoids one comparison in each loop iteration.
This results in smaller code (60 bytes for x86_64, gcc).
