[mlir][bufferization] Add bufferization.dealloc canonicalizer to remove unused alloc-dealloc pairs

Deallocation operations where the allocated value is the 'memref' and
'retained' list are currently not supported. This is because when values
are in the retained list, they typically have a use-site at a later
point and another deallocation op exists at that later point to free the
memref then. There alrady exists a canonicalization pattern in the
buffer deallocation simplification pass that removes the allocated value
from the earlier dealloc because it will never be actually deallocated
in that case and thus does not have to be considered in this new
pattern.

The LLVM Compiler Infrastructure

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, or #llvm IRC channel on OFTC.

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