050cc1cd6e [mlir] Add InitializeNativeTargetAsmParser to ExecutionEngine.
This is required to allow python to work with lowerings that use inline_asm.

c8b8e8e022 [MLIR] Execution engine python binding support for shared libraries
Add support to Python bindings for the MLIR execution engine to load a
specified list of shared libraries - for eg. to use MLIR runtime
utility libraries.

185ce8cdfc [MLIR][PYTHON] Provide opt level for ExecutionEngine Python binding
Provide an option to specify optimization level when creating an
ExecutionEngine via the MLIR JIT Python binding. Not only is the
specified optimization level used for code generation, but all LLVM
optimization passes at the optimization level are also run prior to
machine code generation (akin to the mlir-cpu-runner tool).

Default opt level continues to remain at level two (-O2).

Contributions in part from Prashant Kumar <prashantk@polymagelabs.com>

7a4d630764 Add a "register_runtime" method to the mlir.execution_engine and show calling back from MLIR into Python
This exposes the ability to register Python functions with the JIT and
exposes them to the MLIR jitted code. The provided test case illustrates
the mechanism.

19db802e7b [mlir] make implementations of translation to LLVM IR interfaces private
There is no need for the interface implementations to be exposed, opaque
registration functions are sufficient for all users, similarly to passes.

13cb431719 Add basic JIT Python Bindings
This offers the ability to create a JIT and invoke a function by passing
ctypes pointers to the argument and the result.

86c8a7857d Add C bindings for mlir::ExecutionEngine
This adds minimalistic bindings for the execution engine, allowing to
invoke the JIT from the C API. This is still quite early and
experimental and shouldn't be considered stable in any way.
