Reapply "[lld] enable fixup chains by default (#79894)" (#99255)

This reverts commit f55b79f59a77b4be586d649e9ced9f8667265011.

The known issues with chained fixups have been addressed by #98913,
#98305, #97156 and #95171.

Compared to the original commit, support for xrOS (which postdates
chained fixups' introduction) was added and an unnecessary test change
was removed.

----------
Original commit message:

Enable chained fixups in lld when all platform and version criteria are
met. This is an attempt at simplifying the logic used in ld 907:


https://github.com/apple-oss-distributions/ld64/blob/93d74eafc37c0558b4ffb88a8bc15c17bed44a20/src/ld/Options.cpp#L5458-L5549

Some changes were made to simplify the logic:
- only enable chained fixups for macOS from 13.0 to avoid the arch check
- only enable chained fixups for iphonesimulator from 16.0 to avoid the
arch check
- don't enable chained fixups for not specifically listed platforms
- don't enable chained fixups for arm64_32

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
