• SR-10931 Optional initialization inconsistent between Optional vs T?

Issue Description:

String and Double optional values intialized to nil are getting POed as:

1> class Foo<T,U> {
var t: T?
var u: U?
init() { t = nil; u = nil }
init(_ x: T, _ y: U) { t = x; u = y }
};(Foo<String,Double>(),Foo<Double,String>(3.14,"hello"))
1> class Foo<T,U> {
2. var t: T?
3. var u: U?
4. init() { t = nil; u = nil }
5. init(_ x: T, _ y: U) { t = x; u = y }
6. };(Foo<String,Double>(),Foo<Double,String>(3.14,"hello"))
$R0: (Foo<String, Double>, Foo<Double, String>) = {
0 = {
t = ""
u = 0
}
1 = {
t = 3.1400000000000001
u = "hello"
}
}

Note the default initializer of the class instance should have had t and u print out as nil.
