Issue Description:

Compare this

import Foundation
let unit: () = ()
let unitAny = unit as Any
let unitObject1 = unit as AnyObject
let unitObject2 = unit as AnyObject
unit == unit                      // true
unitObject1.isEqual(unit)         // false
unitObject1.isEqual(unitObject1)  // true
unitObject1.isEqual(unitObject2)  // false

with

import Foundation
let num = 12345678987
let numAny = num as Any
let numObject1 = num as AnyObject
let numObject2 = num as AnyObject
num == num                      // true
numObject1.isEqual(num)         // true
numObject1.isEqual(numObject1)  // true
numObject1.isEqual(numObject2)  // true

I expect all expression in the first code block to be true analogous to the second code block.
