While investigating a customer issue I was missing basic process related memory information in the hs-err files. Things like virtual size and RSS. 

These seem rather fundamental, and we should have them.

Fix Request: Important to fix because: Added memory information helps us with support Nature of fix: In hs-err file printing, reads values for process rss and virtual size from proc file system and prints it out Low risk because: Patch has been active in head for half a year. It it is a small, isolated piece of coding with little to no dependencies to the rest of the VM. Applies cleanly: Only with fuzz=3 since the surrounding code changed too much.
