[VPlan] Run recipe removal and simplification after optimizeForVFAndUF. (#125926)

Run recipe simplification and dead recipe removal after VPlan-based
unrolling and optimizeForVFAndUF, to clean up any redundant or dead
recipes introduced by them. Currently this is NFC, as it removes the
corresponding removeDeadRecipes run in optimizeForVFAndUF and no
additional simplifications kick in after unrolling yet. That is changing
with https://github.com/llvm/llvm-project/pull/123655.

Note that with this change, pattern-matching is now applied after
EVL-based recipes have been introduced.

Trying to match VPWidenEVLRecipe when not explicitly requested might
apply a pattern with 2 operands to one with 3 due to the extra EVL
operand and VPWidenEVLRecipe being a subclass of VPWidenRecipe.

To prevent this, update Recipe_match::match to only match
VPWidenEVLRecipe if it is in the requested recipe types (RecipeTy).

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.
