target/tricore: Fix OPC2_32_RRRR_DEXTR
if cpu_gpr_d[r3] == 0 then we were shifting the lower register to the
right by 32 which is undefined behaviour. In this case the TriCore would
do nothing an just return the higher register cpu_reg_d[r1]. We fixed
that by detecting whether cpu_gpr_d[r3] was zero and cleared the lower
register.
