Runtime: Add +description and ±_copyDescription to SwiftObject. +description missing was an oversight. NSError apparently uses the _copyDescription SPI on NSObject to get the description of its userInfo object. Lift the implementation from NSObject, which apparently really retains rather than copies the description. Fixes rdar://problem/19899687. Swift SVN r25428
