                    obtain previous sibling
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal

There is no need for an extra register to get the previous sibling.
We can use immediate value for the pointer mask in AND.
