Michael Munday 8afa8a3374 cmd/compile: use 32-bit comparisons where possible on s390x 
We use 32-bit operations for 8- and 16-bit arithmetic, so use them
for comparisons too. This won't change performance but it is more
consistent and makes testing 8- and 16-bit comparison codegen
slightly more straightforward (for follow up CL).

Also fix a typo and add some additional double sign and zero
extension rules to remove the operations inserted by the comparison
rules.
