Private members being emitted to definition file

[mtraynham]

If they are supposed to be emitted, they are un-typed.

Seen in 1.4.1 and master.

Example:

Test.ts:

class Test {
    private static BAR: string = 'BAR';
    private _foo: string = 'foo';
}
export = Test;

tsc -d --target ES5 --module commonjs Test.ts

Test.d.ts:

declare class Test {
    private static BAR;
    private _foo;
}
export = Test;

This was found when overloading a superclasses' setter/getter.

Throws error:
Class 'SubClass' incorrectly extends base class 'SuperClass'. Types have separate declarations of a private property '_foo'.

Parent project:

class ObjectA {
    public value: any;
}
class SuperClass {
    private _foo: ObjectA;
    public get foo(): ObjectA {
         return _foo;
    }
}

Parent defintiion:

declare class ObjectA {
    private value: any;
}
declare class SuperClass {
    private _foo;
    public foo: ObjectA;
}

Child project:

class ObjectB extends ObjectA {
    public value2: any;
}
class SubClass {
    private _foo: ObjectB;
    public get foo(): ObjectB {
         return _foo;
    }
}

This is by design, see #1532.

Interesting. Thanks for the link. I couldn't seem to find an issue that related.
