[mlir] Add bubbling patterns for non intersecting reshapes (#103401)

Refactored @Max191's PR https://github.com/llvm/llvm-project/pull/94637
to move it to `Tensor`

From the original PR
>This PR adds fusion by expansion patterns to push a tensor.expand_shape
up through a tensor.collapse_shape with non-intersecting reassociations.
Sometimes parallel collapse_shape ops like this can block propagation of
expand_shape ops, so this allows them to pass through each other.

I'm not sure if I put the code/tests in the right places, so let me know
where those go if they aren't.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

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.

Getting the Source Code and Building LLVM

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.

Getting in touch

Join the LLVM Discourse forums, Discord chat, LLVM Office Hours or Regular sync-ups.

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