fix(es/compat): Split declaration and init in block-scoping pass

[kdy1]

Description:

This does not support

class Foo extends Bar {
    constructor() {
        for (const i of [1]) {
            setTimeout(() => {
                console.log(this)
            });
        }
        super();
    }
}

but it does not seem to be used in a real-world code.
