Issue Description:

let dc = DateComponents(hour: 5, minute: 2)
print(dc.value(for: .second))

/// The calendar and timeZone and isLeapMonth property values cannot be retrieved by this method.
public func value(for component: Calendar.Component) -> Int?

Returns: Optional(9223372036854775807) instead of nil

p.s. the whole "isLeapMonth" thing for EVERY DATE COMPONENTS is really annoying

Comment by David Dunn (JIRA)

I debugged through the code and found that this issue happens for any component that you haven't explicitly given a value to. All values that should be nil seem to get replaced with the value of Int.max.

However this happens on both Mac and Linux it seems, so as far as I can tell it's expected behavior? Although it does seem somewhat strange, it would be nice to get input from Apple on this.
