The await expression:
await 1 ? 2 : 3
is equivalent to:(await 1) ? 2 : 3
so parens must be emitted for:await (1 ? 2 : 3)
Bizarrely, this is not the same as yield expressions, where:
yield 1 ? 2 : 3
is equivalent to:yield (1 ? 2 : 3)
and not equivalent to:(yield 1) ? 2 : 3
I have no idea why the spec is like this 馃槙
