[LLVMdev] Proposal: change LNT’s regression detection algorithm and how it is used to reduce false positives

Motivation: LNT’s current regression detection system has false positive rate that is too high to make it useful. With test suites as large as the llvm “test-suite” a single report will show hundreds of
