@vbvictor I've manually reviewed and submitted the suggestion of the pass for clang, lld and clang-tools-extra. The was only a few debatable situations, mostly due to `std::pair` having a non-trivial move-assign in some circumstances, while not generating better code in those cases. The suggestion is not semantically incorrect, but not actually profitable.
