JIT 后端：通过 Cranelift 把 IR 编译为本机代码，或在 WebAssembly 环境中编译为 WebAssembly。
JIT backend: compiles Entelechy IR to native code through Cranelift, or to WebAssembly where Entelechy is WebAssembly, and runs it on the CPU
JIT backend.
Compiles a Validated module’s functions with Cranelift when the
Kernel is prepared and runs them on as many threads as pay off. The
contract is the CPU interpreter’s, bit for bit: word layout, integer
checks, reads through the scope’s gate, and libm. Native operations
run on the wrapped CPU backend.
When Entelechy is itself WebAssembly, the code is WebAssembly (wasm),
loaded into Entelechy’s function table; a table index stands for a
function pointer.
