Automatically assigning owner based on suspected regression changelist https://chromium.googlesource.com/v8/v8/+/84a71a585a4d4c6e868131b6ab5cb56f163abce2 ([parser] classify binding pattern errors when parsing await expression).

This failure has nothing to do with my CL (It's failing in the preceding commit f3897c7e9e643f639a8772c31087b9f4d98eaeb3). I'm suspicious that clusterfuzz automatically assigns bugs when it finds a non-@google.com/@chromium.com author in a failing patch before finding the actual cause. That's really a very bad thing to do, because it's a detractor for non-googler contributors, and it gets in the way of finding the actual problem.

If I had to guess, it looks related to 59f221740c942f8e7d8cef87b1a09de353ba359a and the related patches after it (possibly only visible after f2e19a63873a700e6c0a1bca35e8301bd50db4e1 (--future in the repro command line), but I don't have time to dig into details and find the proper responsible commit right now.

Very likely this is a duplicate of chromium:793671. I'll validate once the fix for that lands.

Lowering priority, because this is a bug happening under the --future flag only.

ClusterFuzz has detected this issue as fixed in range 50002:50003.
