RFR: 8260198: TypeInstPtr::dump2() emits multiple lines if Verbose is set [v6]

[Xin Liu]

> Add a flag _suppress_cr to outputStream. outstream objects won't emit any CR if it's set.
> Correct TypeInstPtr::dump2 to make sure it only emits klass name once.
> Remove the comment because Klass::oop_print_on() has emitted the address of oop.
