perf vendor events s390: Add metric for TLB and cache
...
Add metrics for tlb and cache statistics:
- finite_cpi: Cycles per Instructions from Finite cache/memory
- est_cpi: Estimated Instruction Complexity CPI infinite Level 1
- scpl1m: Estimated Sourcing Cycles per Level 1 Miss
- tlb_percent: Estimated TLB CPU percentage of Total CPU
- tlb_miss: Estimated Cycles per TLB Miss

perf vendor events s390: Add common metrics
...
Add 3 metrics for s390 machines:
- Cycles per instruction: Amount of CPU cycles used per instructions,
named cpi.
- Problem state ratio: Ratio of instructions executed in problem state
compared to total number of instructions, named prbstate.
- Level one instruction and data cache misses per 100 instructions,
named l1mp.
For details about the formulas see this documentation:

perf json: Add s390 transaction counter definition

'perf stat' displays transactional counters using flag -T on x86. On
s390 use a JSON file defined metric named transaction to achieve the
same result.
