Minify breaks setters with unused arguments

[Arkerthan]

Take this valid javascript:

class Test {
	set x(e) {
		throw  Error("Operation not supported");
	}
}

It minifies to class Test{set x(){throw Error("Operation not supported")}}, expanded:

class Test {
	set x() {
		throw Error("Operation not supported");
	}
}

which is invalid javascript.
