[SLP] avoid 'tmp' value name conflict with auto-generated CHECK script; NFC

The script uses 'TMP#' as its substitute for nameless values,
so if a test already contains 'tmp#' *named* values, then
there could be trouble. We should probably just fix the
script to avoid this problem going forward, but it's easy
enough to change a test too (and explicitly naming variables
'tmp' is always a sad choice).
