RFR 8196740 : Character.digit(int, int) returns wrong value for out of range radix

The recent fix for JDK-8196331 [1] appeared to slightly change the behavior.
Specifically, if the radix is greater than MAX_RADIX then the method may 
return a non-negative value, even though the spec requires it must 
return -1 [2].

Would you please help review the fix?

I suspect that this version may even work a tiny bit faster, as we 
perform less comparisons in a common case.

Thanks in advance!

With kind regards,
