Add IMEMO type to heap dump output.
IMEMO objects have many types. Without this change, we cannot see what types of IMEMO objects are being used when dumping the heap. Adding the type to the IMEMO object will allow us to gather statistics about IMEMO objects being used. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@57486 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
