RFR(XS): JDK-8186154 : Extra info with +LogTouchedMethods

[Eric Caspole]

Hi,
Please review this very small change to add more info to 
+LogTouchedMethods including the touched count and whether the method 
has loops. This extra info has been handy while doing experiments to 
create the most efficient AOT library for quick startup.
