[$] Cranelift code generation comes to Rust

Cranelift is an Apache-2.0-licensed
code-generation backend being developed as part
of the Wasmtime runtime for
WebAssembly.
In October 2023, the Rust project made Cranelift available as an optional
component in its nightly toolchain.
Users can now use Cranelift as the code-generation backend for debug builds of
projects written in Rust,
making it an opportune time to look at what makes Cranelift different.
Cranelift is designed to compete with existing compilers by generating
code more quickly than they can, thanks to a stripped-down design that prioritizes
only the most important optimizations.
