Wait for concurrent sweep tasks before verifying points, as building the allocation set expects unmarked objects. Make assertion okay with a missing stack map at entry, which transiently exists for OSR, as the frame looks the same as unoptimized code here. Fixes #13608 Fixes #23683 Reproduces issue #26927 R=fschneider@google.com Review URL: https://codereview.chromium.org/2411453003 .
