I've started this cleanup more several times now, but got sidetracked elsewhere, e.g. by llvm-exegesis problems. Not this time, finally! This is mainly cleaning up the inverse throughput values, and a few latencies/uops, based on the llvm-exegesis measured values. Though this is not complete by any means, there's certainly more cleanup to be done. The performance numbers (i've only checked by RawSpeed benchmark) aren't really surprising - overall this *slightly* (< -1%) improves perf. llvm-svn: 360341
