RFR: 8035648: Don't use Handle in java_lang_String::print

[Coleen Phillimore]

This looks fine.   It's a leaf function and it's pretty clear that there 
are no safepoints   In the past, we converted all the calls to take 
Handles whenever possible because it saved a lot of re-handleizing and 
bugs with unhandled oops, and we prefer that unless there's a good 
reason.   Here there is a good reason and it's obviously a leaf 
function, so this is fine.  I don't think you should add 
No_Safepoint_Verifier.

Thanks,
Coleen
