LLVM-Z80 is an LLVM fork targeting the Z80 and the SM83. It is a next-generation compiler with highly stable code generation and excellent optimization.

A comparison with SDCC and other C compilers is available here: https://zlfn.github.io/z80-bench

This PR adds LLVM-Z80 to the README.md


Since LLVM-Z80 is a fairly large project, AI coding agents are used in its development and maintenance, as they are in upstream LLVM.

The AI tools involved are quite diverse, so it is hard to say exactly which tool assisted with what.

As far as I know, the AI tools that the other contributors and I have used are:

Claude Opus 4.6, 4.7, 4.8, 5, and 5.5; Claude Sonnet 4.6; Claude Fable 5 and 5.1; GitHub Copilot; OpenAI Codex; and Google Antigravity.

If the parent projects LLVM and LLVM-MOS are included, it would be fair to say that virtually every coding agent in existence has been used.

Looks fair IMO. Thanks! (And extra thanks for doing the LLM disclosure properly 🙏)
