[VPlan] Port invalid cost remarks to VPlan. (#99322)

This patch moves the logic to create remarks for instructions with
invalid costs to work on recipes and decoupling it from
selectVectorizationFactor. This is needed to replace the remaining uses
of selectVectorizationFactor with getBestPlan using the VPlan-based cost
model.

The current implementation iterates over all VPlans and their recipes
again, to find recipes with invalid costs, which is more work but will
only be done when remarks for LV are enabled. Once the remaining uses of
selectVectorizationFactor are retired, we can collect VPlans with
invalid costs as part of getBestPlan if we want to optimize the remarks
case a bit, at the cost of adding additional complexity.

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.
