[LoopInterchange] Add an option to control the cost heuristics applied (#133664)

LoopInterchange has several heuristic functions to determine if
exchanging two loops is profitable or not. Whether or not to use each
heuristic and the order in which to use them were fixed, but #125830
allows them to be changed internally at will. This patch adds a new
option to control them via the compiler option.

The previous patch also added an option to prioritize the vectorization
heuristic. This patch also removes it to avoid conflicts between it and
the newly introduced one, e.g., both
`-loop-interchange-prioritize-vectorization=1` and
`-loop-interchange-profitabilities='cache,vectorization'` are specified.

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.

Getting in touch

Join the LLVM Discourse forums, Discord chat, LLVM Office Hours or Regular sync-ups.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
