After the encoding index instance variable is removed when all

Since 9d9aea7fe50f6340829faa105d9ffe08ebaee658, generic instance

segfault.  Get rid of that segfault by raising an exception, for

This removes the related tests, and puts the related specs behind
version guards.  This affects all code in lib, including some
libraries that may want to support older versions of Ruby.
