* add solver ConvIgemmFwdV6r1DlopsNchwKcyxNkhw; rename static ck source files
* make inner product compatible on gfx900
* Update src/include/miopen/solver/ck_utility_common.hpp
* compiler parameter use stream
* use int instead of index_t in kernel wrapper
* DynamicBuffer, StaticBuffer, amd_buffer_load support customized value for invalid element
* Add dynamic generic reduction kernel layer (kernel wrappers, kernel implementations and utilities)
* Some updates to dynamic composable kernel facility for the need of dynamic generic reduction
* Update to generic reduction C++ host interface layer to support dynamic generic reduction
* Update to remove tidy complaints in host interface layer
* Change the unary operator form from void op(T &x) to T op(T x)
* Update to pass single workspace pointer for all kernels (fix for OpenCL backend)
* Use cppcheck-suppress to prevent some strange warnings
* Re-use operator [] and () for DynamicBuffer and update to depending codes
* Remove useless codes in first call threadwise/warpwise/blockwise kernel wrappers
* [performance] Remove un-needed local buffer initialization
