if width was 0 we would run into the assertion: qemu-system-tricore: tcg/tcg-op.c:217: tcg_gen_sari_i32: Assertion `arg2 >= 0 && arg2 < 32' failed.o The instruction manual specifies undefined behaviour for this case. So we bring this in line with the golden Infineon simlator 'tsim', which simply writes 0 to the result in case of width=0.
