[mlir][Transforms] Support `replaceAllUsesWith` in dialect conversion This commit adds support for `RewriterBase::replaceAllUsesWith` to the dialect conversion. Uses are not immediately replaced, but in a delayed fashion during the "commit" phase. No type conversions are performed; this is consistent with `ConversionPatternRewriter::replaceUsesOfBlockArgument`. - `RewriterBase::replaceAllUsesWith` is now virtual, so that it can be overridden in the dialect conversion. Note: `RewriterBase::replaceOp` can now be turned into a non-virtual function in a follow-up commit. - `ConversionPatternRewriter::replaceUsesOfBlockArgument` is generalized to `ConversionPatternRewriter::replaceAllUsesWith`, following the same implementation strategy. - A new kind of "IR rewrite" is added: `ValueRewrite` with `ReplaceAllUsesRewrite` (replacing `ReplaceBlockArgRewrite`) as the only value rewrite for now. - `replacedOps` is renamed to `erasedOps` to better capture its meaning.

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.
Consult the Getting Started with LLVM page for information on building and running LLVM.
