+Bug 1894423 - Remove unused ExclusiveData move constructor. r=spidermonkey-reviewers,jonco
+
+Because the constructor is actually not used, the compiler used to not
+complain about it being broken. Recent changes on clang trunk made it
+catch this problem without the constructor being used.
+
+As Mutex doesn't have a move constructor, it's also not only a matter of
+adding the missing underscore to lock.
+
+As the constructor is never used, just remove it.
