Issue Description:

1. Steps to reproduce:

var data = Data.init(count: 837933)     // count is larger than Int16.max
data.removeSubrange(0..<834385)         // upperBound is larger than Int16.max

2. Seems that it's crashed in

internal struct InlineSlice {
   ...

   @inlinable // This is @inlinable as a convenience initializer.
   init(_ large: LargeSlice) {
      assert(large.range.lowerBound < HalfInt.max)
      assert(large.range.upperBound < HalfInt.max)
      self.init(large.storage, range: large.range)
   }

   ...
}

Because HalfInt on 32 bits devices is Int16, so assert large.range.upperBound < HalfInt.max is failed.
