Panic on 'for .. of' loop in async function

[cauthmann]

Thanks for your quick work on 598. I tried to run swc over our test-suite to get you some real-world testcases, but got consistent panics on several files. I reduced it to a minimal testcase which consistently panics, both with the official binaries and with npm_config_build_from_source=1, on x64 linux.

The minimal testcase is this:

async function foo() {
	for (let a of b) {
	}
}

Removing the async fixes it, removing the loop (or using a different kind of loop) fixes it.

npx swc --no-swcrc test.js

fatal runtime error: failed to initiate panic, error 5

No way to get a panic message or backtrace, unfortunately. I wish there was a cli binary that didn't go through node..
