Done, it's just `Init->isGLValue()` now. The one lvalue operand that isn't a reference binding is a string literal (or `@encode`) initializing an array element, so that case is excluded; otherwise CodeGen would emit a pointer where the array contents belong. Added both string-literal shapes to the test.
