CompiledIC::is_icholder_entry() uses Vtablestubs::entry_for() on code blobs known to be VtableBlob instances.
All VtableBlobs are managed by Vtablestubs, i.e. such blobs are trivially always in the VtableStubs table.
Specialization of that entry_for() call allows sidestepping locking the mutex for determining this and avoids the always-succeeding search too.
