[11u] 8225141: Better handling of classes in error state in fast class initialization checks

[Zhengyu Gu]

Hi,

I would like to backport this patch, as it is in Oracle 11.0.6 backport.

The patch does not apply cleanly. There are line shifts, also none 11u 
backportable JDK-8215575 merged debug only and non-debug inline versions 
of set_init_thread() method.

Original bug: https://bugs.openjdk.java.net/browse/JDK-8225141

Original code review thread:

11u webrev: http://cr.openjdk.java.net/~zgu/JDK-8225141-11u/webrev.00/

Test:

Thanks,
