The patch gives out the details of the znver2 scheduler model.
Rome is second generation zen family processor. 
There are few improvements with respect to execution units, latencies and throughput when compared with znver1.
The tests that were present for znver1 for llvm-mca tool were replicated. The latencies, execution units, timeline and throughput information are updated for znver2.
I am working on another patch focusing on the information as mandated by exegesis.
