1) fix include directories
2) don't use PCH for source file with custom COMPILE_FLAGS

  * use __GNUC_MINOR__ in correct place to check the version of GCC
  * check processor support of FP16 at run time
  * check compiler support of FP16 and pass correct compiler option
  * rely on ENABLE_AVX on gcc since AVX is generated when mf16c is passed
  * guard correctly using ifdef in case of various configuration
  * use v_float16x4 correctly by including the right header file

- enable C++11
- fix macro

- calculate ticksTotal instead of ticksMean
- local / global width is based on ticksTotal value
- added instrumentation for OpenCL program compilation
- added instrumentation for OpenCL kernel execution

Also put "object" targets to off by default (they doesn't work well)

* remove obsolete paths
* add Pascal arch support
