for await is transpiled to invalid code

[mischnic]

Describe the bug

Transpiling for await produces code that fails with:

                    for(_iterator = lol()[Symbol.iterator](); !(_iteratorNormalCompletion = (_step = _iterator.next()).done); _iteratorNormalCompletion = true){
                                                          ^

TypeError: lol(...)[Symbol.iterator] is not a function

Input code

async function* lol() {
	yield 1;
	yield 2;
}

async function main() {
	for await (const x of lol()) {
		console.log(x);
	}
}
main();

Config

{
	"env": {
		"mode": "entry",
		"coreJs": 3
	}
}

{
	"browserslist": [
		"Safari 9"
	],

		"@swc/core": "^1.2.57",
		"browserslist": "^4.16.6",
		"regenerator-runtime": "^0.13.7"
	}
}
