RFR (S) 8001538: hs_err file does not list anymore compiled methods in compilation events

[Vladimir Kozlov]

Very nice fix, Vladimir I., thank you

To confirm, the size fix restored methods names in compilation events. Right?

You moved deoptimization event logging under resourceMark, make sure the logging code does not use resource area or copied from it to safe place.

Thanks,
Vladimir
