Issue Description:

This code:

import Foundation

let calendar = Calendar.current
let after = Date(timeIntervalSinceReferenceDate: 599529600.0) // i.e., 2020/1/1
let components = DateComponents(year: 2019, month: 1, day: 1, hour: 0, minute: 0, second: 0)
let next = calendar.nextDate(after: after, matching: components, matchingPolicy: .nextTimePreservingSmallerComponents, direction: .forward)
print("The next \(components) after \(after) will be: \(String(describing: next))")

Will output this on osx:

swift linux-check.swift
The next year: 2019 month: 1 day: 1 hour: 0 minute: 0 second: 0 isLeapMonth: false  after 2020-01-01 00:00:00 +0000 will be: nil

But on linux will produce:

swift linux-check.swiftswift linux-check.swiftStack dump:0. Program arguments: /usr/bin/swift -frontend -interpret linux-check.swift -disable-objc-interop -color-diagnostics -module-name main1.
