[VPlan] Add opcode to create step for wide inductions. (#119284)

This patch adds a WideIVStep opcode that can be used to create a vector
with the steps to increment a wide induction. The opcode has 2 operands
* the vector step
* the scale of the vector step

The opcode is later converted into a sequence of recipes that convert
the scale and step to the target type, if needed, and then multiply
vector step by scale.

This simplifies code that needs to materialize step vectors, e.g.
replacing wide IVs as follow up to
https://github.com/llvm/llvm-project/pull/108378 with an increment of
the wide IV step.

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.
