Bug 22145 – scope for foreach parameters is ignored

Using HEAD as of July 26th (67132039c4c792d7722daeb9bef0a305e2f74fb1). ``` int* global; struct Foo { int opApply (scope int delegate (scope int* ptr) @safe dg) @safe { return 0; } } void main () @safe { Foo f; foreach (scope int* x; f) { global = x; } } ``` Compiled with `-dip1000`, it should complain that the assignment violates `scope`, but currently we get: ``` foreach.d(13): Error: function `foreach.Foo.opApply(scope int delegate(scope int* ptr) @safe dg)` is not callable using argument types `(int delegate(int* x) nothrow @nogc @safe)` foreach.d(13): cannot pass argument `__foreachbody2` of type `int delegate(int* x) nothrow @nogc @safe` to parameter `scope int delegate(scope int* ptr) @safe dg` ```

It seems when the compiler creates the foreach delegate, it does not add in `scope` qualifications. This is likely because that part of the implementation is very, very old and has not been touched in a long time.
