Add RUN line for `verify-uselistorder` to every test in `test/Assembly`, unless it's a negative check (assembler rejects it) or verification fails. There are three files that verification fails on (so I've left out the RUN lines): - 2002-08-22-DominanceProblem.ll - ConstantExprFold.ll - ConstantExprFoldCast.ll This is part of PR5680. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@214365 91177308-0d34-0410-b5e6-96231b3b80d8
