This fix basic kernel get wrong running time, i.e. 0ms. - If creating cache directory failed, disable auto-tuning. * Detect and create cache dir on windows Signed-off-by: Li Peng <peng.li@intel.com> * Refine gemm like convolution kernel. Signed-off-by: Li Peng <peng.li@intel.com> * Fix redundant swizzleWeights calling when use cached kernel config. * Fix "out of resource" bug when auto-tuning too many kernels. * replace cl_mem with UMat in ocl4dnnConvSpatial class * OCL4DNN: reduce the tuning kernel candidate. This patch could reduce 75% of the tuning candidates with less than 2% performance impact for the final result. Signed-off-by: Zhigang Gong <zhigang.gong@intel.com> * replace cl_mem with umat in ocl4dnn convolution Signed-off-by: Li Peng <peng.li@intel.com> * remove weight_image_ of ocl4dnn inner product Actually it is unused in the computation Signed-off-by: Li Peng <peng.li@intel.com> * Various fixes for ocl4dnn 1.

Use a set of pre-tuned configs as default config if auto-tuning is disabled. These configs are tuned for Intel GPU with 48/72 EUs, and for googlenet, AlexNet, ResNet-50 If default config is not suitable, use the first available kernel config from the candidates. Candidate priority from high to low is gemm like kernel, IDLF kernel, basick kernel. * dnn(ocl4dnn): pooling doesn't use OpenCL subgroups * dnn(ocl4dnn): fix perf test OpenCV has default 3sec time limit for each performance test.
