Akira Hatanaka 268c0509a9 Fix a bug in which BranchProbabilityInfo wasn't setting branch weights of basic blocks inside loops correctly. ... Previously, BranchProbabilityInfo::calcLoopBranchHeuristics would determine the weights of basic blocks inside loops even when it didn't have enough information to estimate the branch probabilities correctly. This patch fixes the function to exit early if it doesn't see any exit edges or back edges and let the later heuristics determine the weights. This fixes PR18705 and <rdar://problem/15991090>.
