Add a -verify-use-list-order pass, which shuffles use-list order, writes to bitcode, reads back, and verifies that the (shuffled) order matches. - The utility functions live in lib/IR/UseListOrder.cpp. - Moved (and renamed) the command-line option to enable writing use-lists, so that this pass can return early if the use-list orders aren't being serialized. It's not clear that this pass is the right direction long-term (perhaps a separate tool instead?), but short-term it's a great way to test the use-list order prototype. I've added an XFAIL-ed testcase that I'm hoping to get working pretty quickly. This is part of PR5680. llvm-svn: 213945
