(This was a TODO from the initial patch).
The control-flow sink utility accepts a callback that is used to sink an operation into a region.
The `moveIntoRegion` is called on the same operation and region that return true for `shouldMoveIntoRegion`.
The callback must preserve the dominance of the operation within the region. In the default control-flow
sink implementation, this is moving the operation to the start of the entry block.

This has been on _Both for a couple of weeks. Flip usages in core with
intention to flip flag to _Prefixed in follow up. Needed to add a couple
of helper methods in AffineOps and Linalg to facilitate a pure flag flip
in follow up as some of these classes are used in templates and so
sensitive to Vector dialect changes.

- Adds default implementations of `isDefinedOutsideOfLoop` and `moveOutOfLoop` since 99% of all implementations of these functions were identical
- `moveOutOfLoop` takes one operation and doesn't return anything anymore. 100% of all implementations of this function would always return `success` and uses would either respond with a pass failure or an `llvm_unreachable`.

This revision supports padding only a subset of the iteration dimensions via an additional padding-dimensions parameter. This control allows us to pad an operation in multiple steps. For example, one may want to pad only the output dimensions of a producer matmul fused into a consumer loop nest, before tiling and padding its reduction dimension.

Pass the padding options using arrays instead of lambdas. In particular pass the padding value as string and use the argument parser to create the padding value. Arrays are a more natural choice that matches the current use cases and avoids converting arrays to lambdas.

This patch is a cleanup patch that merges PresburgerLocalSpace and
PresburgerSpace. Asserting that there are no locals is shifted to the
users of PresburgerSpace themselves.
The reasoning for this patch is that PresburgerLocalSpace did not contribute
much and only introduced additional complexity as locals could still be present
in PresburgerSpace, just not writable. This could introduce problems if a
PresburgerSpace with locals was copied to PresburgerLocalSpace which expected
no locals in a PresburgerSpace.

This revision introduces a heuristic to stop fusion for shape-only tensors. A shape-only tensor only defines the shape of the consumer computation while the data is not used. Pure producer consumer fusion thus shall not fuse the producer of a shape-only tensor. In particular, since the shape-only tensor will have other uses that actually consume the data.
The revision enables fusion for consumers that have two uses of the same tensor. One as input operand and one as shape-only output operand. In these cases, we want to fuse only the input operand and avoid output fusion via iteration argument.

In LexSimplex, instead of adding equalities as a pair of inequalities,
add them as a single row, move them into the basis, and keep them there.
There will always be a valid basis involving all non-redundant equalities. Such
equalities will then be ignored in some other operations, such as when looking
for pivot columns. This speeds them up a little bit.
More importantly, this is an important precursor patch to adding support for
symbolic integer lexmin, as this heuristic can sometimes make a big difference there.

It is often necessary to "rollback" IntegerRelations to an earlier state. Although providing full rollback support is non-trivial, we really only need to support the case where the only changes made are to append ids or append constraints, and then rollback these additions. This patch adds support to rollback in such situations by recording the number of ids and constraints of each kind and providing support to truncate the IntegerRelation to those counts by removing appended ids and constraints. This already simplifies subtraction a little bit and will also be useful in the implementation of symbolic integer lexmin.
