to their base class BaseMemRefType so that it can be retrieved from it without
downcasting it to the specific memref.

This pass converts shape.cstr_* ops to eager (side-effecting)
error-handling code. After that conversion is done, the witnesses are
trivially satisfied and are replaced with `shape.const_witness true`.

Conversion to LLVM becomes confusing and incorrect if someone tries to lower
STD -> LLVM and only then GPULaunchFuncOp to LLVM separately. Although it is
technically allowed now, it works incorrectly because of the argument
promotion. The correct way to use this conversion pattern is to add to the
STD->LLVM patterns before running the pass.

- Change the default builders to use TypeRange instead of ArrayRef<Type>
- Custom builders defined in LinalgStructuredOps now conflict with the default

this by replicating the collective param builder as a custom builder and skipping
the generation of default builders for these ops.

Blocks in a region and operations in a block are organized in a linked list.
The C API only provides functions to append or to insert elements at the
specified numeric position in the list. The latter is expensive since it
requires to traverse the list. Add insert before/after functionality with low
cost that relies on the iplist elements being convertible to iterators.

Instead of performing a transformation, such pass yields a new pass pipeline
to run on the currently visited operation.
This feature can be used for example to implement a sub-pipeline that
would run only on an operation with specific attributes. Another example
would be to compute a cost model and dynamic schedule a pipeline based
on the result of this analysis.

Change the indexing map to iterate over the (b, x0, x1, z0, z1, q, k) instead of (b, x0, x1, k, q, z0, z1) to evaluate the convolution expression:

This revision allows representing a reduction at the level of linalg on tensors for named ops. When a structured op has a reduction and returns tensor(s), new conventions are added and documented.
As an illustration, the syntax for a `linalg.matmul` writing into a buffer is:
```
linalg.matmul ins(%a, %b : memref<?x?xf32>, tensor<?x?xf32>)
outs(%c : memref<?x?xf32>)
```
, whereas the syntax for a `linalg.matmul` returning a new tensor is:
```
%d = linalg.matmul ins(%a, %b : tensor<?x?xf32>, memref<?x?xf32>)
init(%c : memref<?x?xf32>)
-> tensor<?x?xf32>
```
Other parts of linalg will be extended accordingly to allow mixed buffer/tensor semantics in the presence of reductions.
This op is a catch-all for creating witnesses from various random kinds
of constraints. In particular, I when dealing with extents directly,
which are of `index` type, one can directly use std ops for calculating
the predicates, and then use cstr_require for the final conversion to a
witness.

- Change OpClass new method addition to find and eliminate any existing methods that
are made redundant by the newly added method, as well as detect if the newly added
method will be redundant and return nullptr in that case.
- To facilitate that, add the notion of resolved and unresolved parameters, where resolved
parameters have each parameter type known, so that redundancy checks on methods
with same name but different parameter types can be done.
- Eliminate existing code to avoid adding conflicting/redundant build methods and rely
on this new mechanism to eliminate conflicting build methods.

ConvOp vectorization supports now only convolutions of static shapes with dimensions
of size either 3(vectorized) or 1(not) as underlying vectors have to be of static
shape as well. In this commit we add support for convolutions of any size as well as
dynamic shapes by leveraging existing matmul infrastructure for tiling of both input

In the future this pass can be extended to take "tiling mask" as a user input which
will enable vectorization of user specified dimensions.
