[mlir] Add option to cloning for different results (#184202)

With his permission while he is away, I am resurrecting @zero9178's very
first MLIR PR #65171 that adds an option to change result in the
operation cloning mechanism. This is very useful as cloning is currently
the only way to change the results of an operation.

> Since Operations cannot change the results after creation, a clone is
necessary to create new results. Doing such an operation generically has
not been possible so far. This PR therefore adds a new option to the
CloneOptions struct allowing adding changing the results of the created
operation.
> 
> The caller is responsible to ensure that this is a valid operation and
setting the IRMapping accordingly afterwards if required.

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.
