RFR 8081219: hs_err improvement: Add event logging for class redefinition to the hs_err file

[serguei.spitsyn at oracle.com]

Coleen,

The fix looks good.
But I have a question.
Would it be useful to log the beginning of a redefinition as well so 
that it is known what class is currently being redefined?


Thanks,
Serguei
