Issue Description:
Given the following code:
class ClassA<T> {
init(someVar: Int = 0) {}
}
class ClassB {
private let classA: ClassA<String>
init() {
classA = ClassA<String>()
}
}A source.request.indexsource response does not include a source.lang.swift.ref.function.constructor reference for ClassA<String>() to the declaration init(someVar:). The constructor has the USR s:4test6ClassACACyxGSi7someVar_tcfc and it is not referenced anywhere in the index.
This issue appears to only affect classes with generic types. If I remove the generic type from ClassA, the ClassB constructor declaration will contain a reference to init(someVar:).

@benlangmuir This is also an issue with the index store in Swift 5.3.1.
Also reproduces with indexing while building
$ swift-ide-test --print-indexed-symbols --source-filename /tmp/t.swift

No reference to the initializer.

This also affects generic structs.
