This commit decouples StdlibUnittest from many details of [Contiguous]Array, so tests can give useful feedback even in the presence of a broken [Contiguous]Array implementation while we refactor. Unfortunately, it wasn't practical to make _UnitTestArray use a storage class other than _ContiguousArrayStorage[Base], so we still have to watch out when making changes there. Swift SVN r22875
