target-tricore: Change SSOV/SUOV makro name to SSOV32/SUOV32 

Those makros are exclusively used for 32 bit arithmetics and won't work for
16 bit with two halfwords. So lets get rid of the len parameter and make them
always use 32 bit. Now no token pasting is needed anymore and they can be
regular functions.
