// A `*self` method called directly on an array-index place (`arr[i].method()`)

// now takes the real address of `.index_expr`/`.deref_expr` receivers (via
// `lowerExprAsPtr`), mirroring the explicit-argument path — instead of falling
// through to an alloca+store-of-value that the callee then mutates in vain.
