A tail-call interpreter in (nightly) Rust

The user implemented a tail-call interpreter in Rust using the become keyword, achieving a 40-50% speedup on ARM64 and 2x speedup on x86-64 compared to their previous Rust implementation and hand-coded ARM64 assembly. However, the interpreter still lags behind the assembly backend, and its performance on WebAssembly is significantly worse, with a 1.2-4.6x slowdown compared to native performance.
