feat: with 语句、成员位/移位复合赋值、CALL_NATIVE 无目标修复
with 语句:新增 emit 支持,with 体内自由标识符动态解析(对象属性优先, 回退外层),支持读/写/复合赋值/自增自减/delete/var 初始化动态化, TO_OBJECT opcode 处理原始值对象,顶层 this 绑定全局对象。 复合赋值:新增 6 个 COMPOUND_MEMBER_BIT_* opcode 支持成员位/移位复合赋值, 修复 computed member 复合赋值覆盖 bug,with 内标识符复合赋值动态化。 CALL_NATIVE:实现全局 isNaN/isFinite 并绑定,用户覆盖 builtin 名时 回退通用调用路径而非报错,局部遮蔽 builtin 名走普通 CALL。 test262: with 34 pass(基线 0),compound-assignment 320 pass(基线 223)
