Issue Description:

Large Decimal s don't seem to print correctly in the REPL:

$ swift
Welcome to Apple Swift version 5.5 (swiftlang-1300.0.27.6 clang-1300.0.27.2).
Type :help for assistance.
  1> import Foundation
  2> Decimal.greatestFiniteMagnitude
$R0: Decimal = 3402823669209386527134573422587986984989120495220592886182567909030848074563371292545093099671415093659185923505550104482059460129780644035015876086272801474166652928.000000

  3> print(Decimal.greatestFiniteMagnitude)

The extra precision is not actually present in the backing for the number so it's unclear where LLDB is getting it from.
