ConditionalExpression doesn't parenthesize correctly

[NotWearingPants]

ConditionalExpression is missing a NEEDS_PARENTHESES check.

Using the online demo:

---

(() => {}) ? 2 : 3;

turns into

() => {} ? 2 : 3;

which is a syntax error.

---

({}) ? 2 : 3;

and

({} ? 2 : 3);

turn into

{} ? 2 : 3;

which is a syntax error.

---

(function() {}) ? 2 : 3;

and

(function() {} ? 2 : 3);

turn into

function() {} ? 2 : 3;

which is a syntax error.

---

(class {}) ? 2 : 3;

and

(class {} ? 2 : 3);

turn into

class {} ? 2 : 3;

which is a syntax error.
