Compiler is not correctly work with semicolon

[NikolayMakhonin]

(version: 3.0.0-beta.20)
This code:

<script>
    let time = new Date()
    let timeZone = 'UTC'
    ;(() => {
        const timer = setInterval(() => { time = new Date() }, 1000)
        return () => clearInterval(timer)
    })()
</script>

compiled to:

let time = new Date()(() => {
    const timer = setInterval(() => { time = new Date(); $$invalidate('time', time); }, 1000)
    return () => clearInterval(timer)
})()

But if I put semicolon after 'UTC', it worked correctly

This will be fixed by #3539.
