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
For details about the formulas see this documentation:
