This patch adds two new fields to the perf report generated by the SummaryView. Fields are now logically organized into two small groups; only the second group contains throughput indicators. Example: ``` Iterations: 100 Instructions: 300 Total Cycles: 414 Total uOps: 700 Dispatch Width: 4 uOps Per Cycle: 1.69 IPC: 0.72 Block RThroughput: 4.0 ``` This patch also updates the docs for llvm-mca. Due to the nature of this change, several tests in the tools/llvm-mca directory were affected, and had to be updated using script `update_mca_test_checks.py`. llvm-svn: 340946
