This is similar to the TransformOpInterface move.

[mlir] split transform interfaces into a separate library (#85221)
Transform interfaces are implemented, direction or via extensions, in
libraries belonging to multiple other dialects. Those dialects don't
need to depend on the non-interface part of the transform dialect, which
includes the growing number of ops and transitive dependency footprint.

Split out the interfaces into a separate library. This in turn requires
flipping the dependency from the interface on the dialect that has crept
in because both co-existed in one library. The interface shouldn't
depend on the transform dialect either.

As a consequence of splitting, the capability of the interpreter to
automatically walk the payload IR to identify payload ops of a certain
kind based on the type used for the entry point symbol argument is
disabled. This is a good move by itself as it simplifies the interpreter
logic. This functionality can be trivially replaced by a
`transform.structured.match` operation.

[mlir][transform] Add elementwise criteria to match.structured.body (#79626)
As far as I am aware, there is no simple way to match on elementwise
ops. I propose to add an `elementwise` criteria to the
`match.structured.body` op. Although my only hesitation is that
elementwise is not only determined by the body, but also the indexing
maps. So if others find this too awkward, I can implement a separate
match op instead.

[mlir][transform] Add transform.get_operand op (#78397)
Similar to `transform.get_result`, except it returns a handle to the
operand indicated by a positional specification, same as is defined for
the linalg match ops.

Additionally updates `get_result` to take the same positional specification.
This makes the use case of wanting to get all of the results of an
operation easier by no longer requiring the user to reconstruct the list
of results one-by-one.

[mlir][transform] Check for invalidated iterators on payload values (#66472)
Same as #66369 but for payload values. (#66369 added checks only for
payload operations.)

It was necessary to change the signature of `getPayloadValues` to return
an iterator. This is now similar to payload operations.

Fixes an issue in #66369 where the `LLVM_ENABLE_ABI_BREAKING_CHECKS`
check was inverted.

34a35a8b24 [mlir] Move FunctionInterfaces to Interfaces directory and inherit from CallableOpInterface
Functions are always callable operations and thus every operation
implementing the `FunctionOpInterface` also implements the
`CallableOpInterface`. The only exception was the FuncOp in the toy
example. To make implementation of the `FunctionOpInterface` easier,
this commit lets `FunctionOpInterface` inherit from
`CallableOpInterface` and merges some of their methods. More precisely,
the `CallableOpInterface` has methods to get the argument and result
attributes and a method to get the result types of the callable region.
These methods are always implemented the same way as their analogues in
`FunctionOpInterface` and thus this commit moves all the argument and
result attribute handling methods to the callable interface as well as
the methods to get the argument and result types. The
`FuntionOpInterface` then does not have to declare them as well, but
just inherits them from the `CallableOpInterface`.
Adding the inheritance relation also required to move the
`FunctionOpInterface` from the IR directory to the Interfaces directory
since IR should not depend on Interfaces.

e444dcef7c [mlir][Transform] Add classify_convolution_dims op
Includes `inferConvolutionDims` based on the existing helper for
contractions, `inferContractionDims`. This allows matching and
identifying the relevant dims for a convolution sub-computation of
a linalg operation.

Additionally adds stride/dilations inference to the captures and
convolution interface matcher.

cd9bacdf7f [mlir] generalize matchers to support batch matmul
Mostly the same logic applies, with a different rank.

Additionally expose the logic to do identify contraction dimensions and
contraction-like bodies as independent transform ops. This allows us to
recognize "generic" operations and not only the named ones.

Rework the contraction body matching logic to no longer rely on
contraction operations beign uniquely named.

2fe4d90cac [mlir] make structured transform ops use types
Types have been introduced a while ago and provide for better
readability and transform-time verification. Use them in the ops from
the structured transform dialect extension.

In most cases, the types are appended as trailing functional types or a
derived format of the functional type that allows for an empty right
hand size without the annoying `-> ()` syntax (similarly to `func.func`
declaration that may omit the arrow). When handles are used inside mixed
static/dynamic lists, such as tile sizes, types of those handles follow
them immediately as in `sizes [%0 : !transform.any_value, 42]`. This
allows for better readability than matching the trailing type.

Update code to remove hardcoded PDL dependencies and expunge PDL from
structured transform op code.

0e37ef08d4 [mlir][transform] Use TrackingListener-aware iterator for getPayloadOps
Instead of returning an `ArrayRef<Operation *>`, return at iterator that skips ops that were erased/replaced while iterating over the payload ops.

This fixes an issue in conjuction with TrackingListener, where a tracked op was erased during the iteration. Elements may not be removed from an array while iterating over it; this invalidates the iterator.

When ops are erased/removed via `replacePayloadOp`, they are not immediately removed from the mappings data structure. Instead, they are set to `nullptr`. `nullptr`s are not enumerated by `getPayloadOps`. At the end of each transformation, `nullptr`s are removed from the mapping data structure.

5550c82189 [mlir] Move casting calls from methods to function calls
The MLIR classes Type/Attribute/Operation/Op/Value support
cast/dyn_cast/isa/dyn_cast_or_null functionality through llvm's doCast
functionality in addition to defining methods with the same name.
This change begins the migration of uses of the method to the
corresponding function call as has been decided as more consistent.

Note that there still exist classes that only define methods directly,
such as AffineExpr, and this does not include work currently to support
a functional cast/isa call.

Caveats include:
- This clang-tidy script probably has more problems.
- This only touches C++ code, so nothing that is being generated.

Context:
- https://mlir.llvm.org/deprecation/ at "Use the free function variants
  for dyn_cast/cast/isa/…"
- Original discussion at https://discourse.llvm.org/t/preferred-casting-style-going-forward/68443

Implementation:
This first patch was created with the following steps. The intention is
to only do automated changes at first, so I waste less time if it's
reverted, and so the first mass change is more clear as an example to
other teams that will need to follow similar steps.

Steps are described per line, as comments are removed by git:
0. Retrieve the change from the following to build clang-tidy with an
   additional check:
   https://github.com/llvm/llvm-project/compare/main...tpopp:llvm-project:tidy-cast-check
1. Build clang-tidy
2. Run clang-tidy over your entire codebase while disabling all checks
   and enabling the one relevant one. Run on all header files also.
3. Delete .inc files that were also modified, so the next build rebuilds
   them to a pure state.
4. Some changes have been deleted for the following reasons:
   - Some files had a variable also named cast
   - Some files had not included a header file that defines the cast
     functions
   - Some files are definitions of the classes that have the casting
     methods, so the code still refers to the method instead of the
     function without adding a prefix or removing the method declaration
     at the same time.

3fe7127d48 [mlir] add structured (Linalg) transform op matchers
Add a set of transform operations into the "structured" extension of the
Transform dialect that allow one to select transformation targets more
specifically than the currently available matching. In particular, add
the mechanism for identifying the producers of operands (input and init
in destination-passing style) and users of results, as well as
mechanisms for reasoning about the shape of the iteration space.

Additionally, add several transform operations to manipulate parameters
that could be useful to implement more advanced selectors. Specifically,
new operations let one produce and compare parameter values to implement
shape-driven transformations.

New operations are placed in separate files to decrease compilation
time. Some relayering of the extension is necessary to avoid repeated
generation of enums.
