Subject: [PATCH] Issue #2234 - Part 2: Ensure that the created async function
 wrapper is valid

This excludes the GC-related changes (cell pointer asserts) since we don't have them. This bug should be revisited if we'd ever plan on porting those asserts over.

Partially based on https://bugzilla.mozilla.org/show_bug.cgi?id=1402649
