[mlir][linalg] Produce canonical linalg.generic for im2col (#134675) Before this patch, the Img2Col transform produced a non-canonical linalg.generic whose input tensor was not reported in the inputs of the operation: instead, it was accessed manually from inside the op body, after an internal calculation of the access offsets. This patch modifies the Im2Col rewrite to produce a canonical linalg.generic whose input is correctly reported in its 'ins()', whose access offsets are computed through an indexing map, and whose body contains only a 'linalg.yield' op.

Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
Consult the Getting Started with LLVM page for information on building and running LLVM.
For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
