* Changed required image_shape type from u64 to float

* Proposal op was adjusted

* Clang styles applied

* Added missing new line

* Fixed problem with narrowing conversion

* Code review remarks

* Removed checking types of Proposal input params

* Removed unused input element type variables

* Separate dynamic loading from static linking

* Missed find_my_pathname

* Add method to check if an Executable can create tensors

* Add a Backend check to see if Executable can create tensors

* Update per review comment

* style

* Possible fix so that backend does not keep holding on to the dummy ng_exec

This PR starts the modular approach that we discussed to enable
clang-format on comments so that they are automatically formatted
instead of having to do that manually. It only covers the src/contrib
directory.

* Use f64 APFloat

* PR feedback

* [MLIR] Disable support for boolean type in MLIR

Ops on boolean types are currently not supported by MLIR Compiler until
the proper i1<->i8 type conversion mechanism is in place.

* Add example.

* Fix typo

* Stage README for review pre-release

* Latest README graphic

* Update links on README

* Copy outputs only if the use is outside the sub-graph

* Use unordered_set find

* Fix cycle detection during sub-graph construction

* small refactor

* style-apply

* - Add graph pass method for onnx lstmcell rewrite with lstm cpu op
- insert reshapes to keep the weights in ldigo format
- test case for onnx LstmCell to CPU Lstm

* fix typo

* - check LSTMCell for the fused op decomposistion in the backend

* - fix bug in onnx_lstm graph pass
- passes unit test

* style-fix

* - fix compilation error
- use IFCO gate ordering for bias

*  - Skip LSTMCell to LSTM CPU fusion for peephole

* - add comment && remove duplicate function

* -use dynamic_pointer_cast to check for constant

* - onnx bias will be of shape (2 * gates_count * hidden_size) bias of Wb and Rb are concatenated, we will split the bias, add and rearrange in order IFCO

* - Use most derived LSTM ctor for pattern matching

* - Style Fix

* style fix

* Address PR comments

* - add support for graph pass (MKLDNN version > 1) for mapping LSTMCell -> LSTM CPU op

* Fix merge artifact

* Review fix I

* Review Fix PyAPI

Python rounding is not supported yet in nGraph dialect.

CPU fusion is disabled in MLIR since fused ops are not supported in
nGraph dialect. CPU debug tracer test doesn't expect CompiledKernel ops
generated for MLIR.

    LLVM dialect and translation: support global strings

* [MLIR] Set optimization level for LLVM optimizer and codegen

Now both LLVM optimizer and codegen are aligned with
"NGRAPH_MLIR_OPT_LEVEL" macro.

* [MLIR] Enable LLVM vectorization by initializing TTI

This is the final piece to enable LLVM vectorization for MLIR compiler.
The PR refactors the creation of a target machine in MLIRCompiler so that
we can use it to initialize TargetTransformInfo with the proper host
features and LLVM Loop Vectorizer can get the right vector register
information of the target CPU.

* Axes input was added to LRN

* Unit tests for axes shape check were added

* LRN node deserialization was updated

* Fixed EOF and clang style applied

* Changed Constant to Parameter type in unit tests

* Fixed LRN assert description

* Fixed copy_with_new_args

* Clang style applied

* wip

* parse working with one test

* Add version information query and unit tests for parsing version strings

* add more comments
