Using ArrayRef introduces issues with the order of evaluation between a constructor and
the arguments of the subsequent calls to the `operator()`.
As a consequence the order of captures is not well-defined can go wrong with certain compilers (e.g. gcc-6.4).
This CL fixes the issue by using lambdas in lieu of ArrayRef.

TensorContractionBase has become too unwieldy with all the CRTP manipulation once less trivial transformations are implemented.
This CL drops CRTP for inheritance and uses the same name comparison trick to figure out what to cast into.
As a byproduct, all the -inl.h files disappear.
To maintain the separation between directories, a LINALG_STEP variable is introduced

This CL adds declarative tiling support in the linalg dialect by providing:
1. loop tiling on linalg ops by simply calling into mlir::tile
2. view tiling on linalg ops by:
a. computing the subview between for each tile dimension based on the loop tile size and the mapping of loops to operand ranges.
b. declaring that the tiled form of a tensorcontraction is the same tensorcontraction on subviews, which essentially gives us a recursive form.
Point 2.b is potentially subject to change in the future.
