Subject: [PATCH] emscriptenaudio: Don't bother undefining things about to be
unreachable.
Since the top-level table is getting undefined, all the things in it will
be unreachable and eligible for garbage collection without explicitly
nulling them out.
(cherry picked from commit 5191b20541fce0e3b3071124ced69c31fcaeb783)
