Subject: [trace] Fix errors when handling command arguments

https://reviews.llvm.org/D128453 recently added some safety checks for
command arguments. Unfortunately, some few commands started failing due
to that, and this diff fixes it. But fortunately, the fix is trivial, which is
simply declaring the argument that these commands will receive.
