[PATCH] D139335: [BOLT] Fix blocks layout reverse iterators

[Vladislav Khmelevsky via Phabricator via llvm-commits]

yota9 added a comment.

@Amir Currently these iterators are almost unused - I see them used only under opts::ReportBadLayout right now. After I've tried to use them by my self I've found out that there are some problems with them, e.g. BBs hasInstructions() assert appeared. Anyway it does not look like it is right to use end() block iterator as an reverse begin...
