[mlir][affine] Add pass --affine-raise-from-memref (#138004)

This adds a pass that converts memref.load/store into affine.load/store.
This is useful as those memref operators are ignored by passes like
--affine-scalrep as they don't implement the
Affine[Read/Write]OpInterface. Doing this allows you to put as much of
your program in affine form before you apply affine optimization passes.

This also slightly changes the implementation of affine::isValidDim. The
previous implementation allowed values from the iter_args of affine
loops to be used as valid dims. I think this doesn't make sense and what
was meant is just the induction vars. In the real world, there is little
reason to find an index in the iter_args, but I wrote that in my tests
and found out it was treated as an affine dim, so corrected that.

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.
