[cs] -D erase-generics problem

[nadako]

var arr = [1,2,3];
arr;
cs.system.Array.Sort(@:privateAccess arr.__a, 0, arr.length);

generates

 global::System.Array.Sort(((int[]) (((object[]) (arr.__a) )) ), ((int) (0) ), ((int) (arr.length) ));

which then fails to compile by c# compiler

I don't think there's anything we can do in here. It's the age-old problem of dealing with type parameters and native arrays on java/c#. Any ideas, @nadako ?

Not really...

	static public function test(i:Int) {}
}

class Arr<T> {
	public var arr:NativeArray<T>;

src/Main.cs(30,33): error CS0030: Cannot convert type `object[]' to `int[]'
Compilation failed: 1 error(s), 0 warnings

Generated cs for the failing line:

global::Main.test(((int[]) (a.arr) )[0]);

We need to generate (int)(a.arr[0]) Instead of casting a native array itself.

I kind of "fixed" this for NativeArray specifically. But fixing it in general seems impossible.

Closing old C# issue that won't be addressed.
