With new pm becomes the default, the old-style test command becomes exactly the same as the new test command, i.e. the two commands are now redundant. We should just delete the old command. (unless someone wants to add enable-new-pm=0 to all old commands. Differential Revision: https://reviews.llvm.org/D104895
