Zachary D. Rowitsch a534ff41d2 Implement generators and iterator protocol for bytecode VM (§3.2) ...

Adds full ECMAScript generator support end-to-end: parser recognizes
function*/yield/yield* syntax, the bytecode compiler emits MakeGenerator,
Yield, YieldStar, and GeneratorReturn opcodes, and the VM implements
ECMAScript §27.5 generator state machines with scope save/restore across
yield points so local variables survive suspension. The iterator protocol
(bc_get_iterator/bc_iterator_next) is generalized to dispatch through
GeneratorObject.next(), and generator objects implement Symbol.iterator
returning themselves. Fourteen new bytecode-path tests cover basic
yields, parameters, for-of, independent instances, .return()/.throw(),
and generator expressions.
