RFR: 8367949: JFR: MethodTrace double-counts methods that catch their own exceptions [v2]

[Erik Gahlin]

> Could I have a review of a PR that changes how the instrumentation of the MethodTrace and MethodTiming events is implemented, so they handle exceptions in a better way? 
> 
> For constructors, the current implementation is still used in certain corner cases. A proper implementation would require data-flow analysis, but for all practical purposes this code should work fine.
> 
> Testing: jdk/jdk/jfr
> 
> Thanks
