[PATCH] D32884: [LazyValueInfo] Avoid unnecessary copies of ConstantRanges

[Noel Grandin via Phabricator via llvm-commits]

grandinj added a comment.

if anyone is interested, I wrote a clang plugin for the LibreOffice codebase to find methods that can return a const ref.

Make a big reference to some of our code.

Note that the output of this plugin is not 100% perfect, needs manual confirmation
