[PATCH] D110438: [BPI] Keep BPI available in loop passes through LoopStandardAnalysisResults

[Anna Thomas via Phabricator via llvm-commits]

Thank you for the reviews. I will precommit the test case and update this diff. The point to note is that since Loop predication didn't preserve BPI, we were recalculating it every time for the NPM. We are primarily interested in the NPM, so I'll be adding the testcase for this along with -debug-only=branch-prob, which shows that before this change, we calculate BPI every time we call Loop predication.
