PR jit/63854: Fix leaks in toyvm.c
gcc/jit/ChangeLog:
PR jit/63854
* docs/examples/tut04-toyvm/toyvm.c
(toyvm_compiled_function): New typedef.
(toyvm_compiled_func) Rename to...
(toyvm_compiled_code) ...this.
(struct toyvm_compiled_function): New struct.
(toyvm_function_compile): Return a toyvm_compiled_function *
rather than a toyvm_compiled_func, so that the caller can fully
clean things up. Free "funcname".
(test_script): Update for change to toyvm_function_compile.
Clean up the toyvm_compiled_function.
(main): Likewise.
(docs/intro/tutorial04.rst): Update to reflect the above changes,
and to better spell out the lifetime of the compiled code.
