AnnieSld opened PR #13770 from AnnieSld:cranelift-modernize-docs to bytecodealliance:main:

While reviewing the Cranelift documentation I found several guides that
no longer matched the current codebase.
Addresses #4135 issue

New pages added:

• backend-architecture.md: Documents the CLIF-to-VCode-to-binary
  pipeline and the current roles of ISLE, regalloc2, and MachInst.

• add-new-backend.md: Step-by-step guide for creating a new ISA
  backend: directory layout, registration, settings, MachInst trait,
  PRegSet usage, ABI, ISLE lowering rules, and tests.

• add-clif-instruction.md: Guide for adding a new CLIF opcode:
  instruction format API, builder methods, generated file names,
  verifier checks, and interpreter support.

• add-machine-instruction.md: Guide for adding a machine
  instruction variant: register access in emit(), ISLE file paths,
  and testing commands.

• debugging-codegen.md: Guide for debugging the code generator
  using RUST_LOG, clif-util, and chaos mode.

Updates to existing pages:

• testing.md: Replaced the deprecated test legalizer command
  with test compile, updated the RISC-V feature flag name, and
  corrected the CRANELIFT_TEST_BLESS environment variable.

• index.md: Refreshed guide descriptions and restored the missing
  link to isle-integration.md.

• compare-llvm.md: Updated the description of the current
  compilation pipeline.

I wanted to apologize for my previous PR. I submitted too many changes at once. I've since gone back, studied the codebase more carefully, and I'm reopening this as a smaller, more focused PR with only the changes I personally verified against the current source files.
