#37501
#37501

These tests exercise feature "_json" of runtime/parrot/library/JSON.imc,
which dumps Parrot objects in JSON format as defined at
http://www.json.org/

This patch (against revision 9532) extends t/library/json.t from 2 to 18
tests, of which 2 are marked TODO because the current output, although
JSON-compliant, is untidy.
