Data.replaceSubrange crashes on devices 32 bits

[nghiahoangdev (Hoàng Văn Nghĩa)]

1. Steps to reproduce:

Environment: Latest Swift (happens on earlier version as well), Xcode version, device 32 bits.

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.
