RFR: JDK-8151603: Use error stream instead of tty for logging before ShouldNotReachHere()

[Bengt Rutisson]

Hi everyone,

Could I have a couple of reviews for this change?

http://cr.openjdk.java.net/~brutisso/8151603/webrev.00/
https://bugs.openjdk.java.net/browse/JDK-8151603

Some code dumps information on tty before calling ShouldNotReachHere(). 
With the new logging framework it makes sense to move this to the error 
stream.

Thanks,
Bengt
