perf tools: Support user regs and stack in sample parsing
Adding following info to be parsed out of the event sample:
- user register set
- user stack dump
Both are global and specific to all events within the session.
This info will be used in the unwind patches coming in shortly.
Adding simple output printout (report -D) for both register and
stack dumps.
