These tests use `--check-prefix=CHECK-%os` but then didn't have a CHECK line for every os. In most tests, the linux expectations were sufficient (they match the "wrap_" prefix with .*), so just remove the check-prefix there. In the places where this didn't easily work, make sure there are at least CHECK-Windows and CHECK-Darwin lines.
