* Add CPU horizontal fusion pass for inception.

* Name change.

* Move horizontal fusion to cpu_fusion.

* Change horizontal fusion pass for inception to a general horizontal fusion pass.
Add a unit test conv_horizontal_fusion to cpu_fusion.

* Rename files.

* Correct cpu_fusion.hpp.

* Add NGRAPH_DEBUG.

* Set native layout when input format of slice is nChw16c or nChw8c and lower bound of
channels is not a multiple of 16 or 8.

* added stream writers to dump meta information related to CONSTANT, INTERMEDIATE, PARAMETER's

* WIP added method to dump Input and output reference address in to debug manifest from cpu_call_frame

* added suppport to dump memory refernce in the debug manifest

* - added macro to dump debug manifest
- added support to release_function once dumping the memory references

* added a method to write a generated stream to a file

* dont release function, if NGRAPH_DEX_DEBUG flag set

* Addressed PR comments
-   dump debug manifest using stringstream instead of CodeWriter
-   Moved dumping debug manifest logic to cpu_external_function

* revert changes to call_frame

* - Addressed PR comments

* :Remove call_once from dumping debug_manifest

* address PR comments

* address PR comments

* extend concat elimination to fold slice + reshape

* relax branch tip to be anything not just goe

* add support for transpose when concat of slice + reshape occurred on internal axis.

* simplify reshape order permutation

* multi-axis slice + concat do not cancel and are now disabled. generalize detection of axis reordering when intermediate reshape is present
to include logical reshape and reshape that results in axis reordering for the cases: parent_shape.size gt, eq, and lt concat_shape.size.

* check that slices are in order

* add one user check on reshape

* add more checks

* fix warnings

* Reshape axis order did not include enough dimensions when the transposed and reshaped result was of lower rank.

* inject details into visualize_tree pass

* address bob's feedback

* revert back to map

* - fixed performance_counter for CPU DEX

* made changes to start clock @ the first functor and collected perf_counter @ the exceution of last functor for given kernel execution

* - made changes to have max_pool kernel to have exactly one functor
- assert if functor != num_of_ops

* fixed profiler_counter for TBB execution

* avoid unnecessary calculation to enables<map> value

* Addressed PR comments
-   updated "enables" -> list<functors>

* Common pass registration for codegen and Dex
