[mlir][memref] Fix rollback in test case during `convert-to-llvm` (#135958)

This commit is in preparation of the One-Shot Dialect Conversion
refactoring, which removes the rollback from the dialect conversion
framework.

`GenericAtomicRMWOpLowering` (`generic_atomic_rmw`) triggered a rollback
in two test cases. The lowering pattern adds additional basic blocks to
the enclosing operation, which used to be a `func.func` (now
`llvm.func`). Adding a basic block triggers legalization of the op that
owns the basic block. This fails when running
`--convert-to-llvm="filter-dialects=memref"` because no lowering
patterns for the `func` dialect were populated and only `llvm` ops are
considered "legal" by the `convert-to-llvm` pass, causing a rollback of
the entire `GenericAtomicRMWOpLowering` pattern.

Also add extra `CHECK-INTERFACE` to make sure that all test cases are
correctly lowered with `--convert-to-llvm="filter-dialects=memref"`.

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
