Fix Linalg tiling for the partial tile case.
This CL prepares for mixing lowering of tiled linalg operations to loops with load and store operations. In particular it is necessary to capture partial tile information in views. This CL makes slice ops during Linalg tiling properly stop at partial tile boundaries by implementing `min` with a `cmpi` and `select` over values of index type.
To be consistent with lowering to loops, the implementation of tiling also drops specifics of accessing values via ranges and instead uses ranges of the form
`[0, dim(view), 1]` for creating view slices. This simplifies the code for the implementation of tiling and utils.
This also allows removing restrictions around needing a View or SliceOp defined in the current function context (as well as all it RangeOps). The restriction removal is tested by making the dot test operate directly on views.
The above is still subject to folding of the linalg.dim operation left for a future CL.
At this time, mixing tiling and lowering to loops all the way to execution is not yet functional because affine.for does not allow arbitrarily defined values of index type as its operands.
The previously introduced linalg.range_intersection was not sufficient to capture the necessary information and still required dealing with max quantities.
A followup CL will remove linalg.range_intersection.

```
%D = linalg.dim %view, constant : !linalg.view<...>
affine.for %ix = %c0 to %D {

```
This form composes correctly with tiling and is also the proper way to emit loops from views that across function boundaries.
The previous version that would extract the range_min/max/step was composing incorrectly with tiling (i.e. would shift by range_min both in the loop bounds and in the slice) and would not work across function boundaries.
The relevant tests are updated and a new test `dot_view`---which lowers to loops from views passed as function parameters---is added.

- This removes a potentially expensive call from the destructor of Function.

Use lambdas for nesting edsc constructs.
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.

Rename "AnyOf" and "AllOf" combined predicates to "Or" and "And", respectively.

ExecutionEngine: drop PassManager integration
Originally, ExecutionEngine was created before MLIR had a proper pass
management infrastructure or an LLVM IR dialect (using the LLVM target
directly). It has been running a bunch of lowering passes to convert the input
IR from Standard+Affine dialects to LLVM IR and, later, to the LLVM IR dialect.
This is no longer necessary and is even undesirable for compilation flows that
perform their own conversion to the LLVM IR dialect. Drop this integration and
make ExecutionEngine accept only the LLVM IR dialect. Users of the
ExecutionEngine can call the relevant passes themselves.
