* Function tune and corresponding testcase.
*Add: Tune function in /src/kernel/cuda/conv.cc and corresponding testcase in test_conv.
*Fix: A little bug of perfRecord using in /src/core/runtime.cc.
* Tune part debug
*Add: recover the code, fixed the commit error.
*Add: some anotations in tune function
* clang formmat test
* Fix: mem leak in CUDA Runtime and Conv
