Bug 22967 – [dip1000] no return ref inference for extended return semantics

When returning a parameter by assignment to the first ref parameter, return scope can be inferred when it's a template/auto function. This is not the case for return ref yet: ``` @safe: struct S() { int* x; this(scope int* x) { this.x = x; } // return scope inferred this(ref int x) { this.x = &x; } // no return ref inferred, error } void main() { S!() s; } ```
