Issue Description:

If you create an executable project using Swift Package Manager and write the following:

import Foundation

let progress = Progress(totalUnitCount: 42)

progress.completedUnitCount = 16

print(progress.debugDescription)

progress.totalUnitCount = 0
progress.completedUnitCount = 0

print(progress.debugDescription)

let progress2 = Progress(totalUnitCount: 42)

progress2.completedUnitCount = 16

print(progress2.debugDescription)

progress2.completedUnitCount = 0
progress2.totalUnitCount = 0

print(progress2.debugDescription)

on macOS, this will run successfully. On Linux, this crashes:

Precondition failed: Attempt to add or subtract invalid fraction: file /home/buildnode/jenkins/workspace/oss-swift-package-linux-ubuntu-18_04/swift-corelibs-foundation/Sources/Foundation/ProgressFraction.swift, line 59
