[CodeGen] Remove experimental deferred spilling from GreedyRegAlloc (#137850)

This experimental option was introduced in 2015 via commit 1192294, and
the target hook was added in 2020 via commit 99e865b6. There does not
appear to have ever been a use of this target hook in tree.

This code is complicating one of the most complicated and hard to
understand parts of our code base, and was an experiment introduced
nearly 10 years ago. Let's get rid of it.

Note that the idea described in the original patch is not neccessarily a
bad one, and we might return to it someday.

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.
