+ SparseArrayEntry's write barrier owner should be the SparseArrayValueMap.
+ https://bugs.webkit.org/show_bug.cgi?id=144067
+
+ Reviewed by Michael Saboff.
+
+ Currently, there are a few places where the JSObject that owns the
+ SparseArrayValueMap is designated as the owner of the SparseArrayEntry
+ write barrier. This is a bug and can result in the GC collecting the
+ SparseArrayEntry even though it is being referenced by the
+ SparseArrayValueMap. This patch fixes the bug.
