Fix order of parameter processing. Note the offsets appear different to the size of the variables being passed but s390x will align parameters on 64-bit boundaries which is why the gbooleans appear to be treated as gulongs. (#11912)

Fix order of parameter processing.

New parameter addition was put in wrong spot in the parameter list. Also the offsets on the stack were incorrect as 32-bit values are placed in 64-bit aligned slots on s390x. Therefore, even though these are gbooleans the appear to be treated as gulongs.
