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.

2023-02-07target/riscv: fix for virtual instr exceptionDeepak Gupta
commit fb3f3730e4 added mechanism to generate virtual instruction exception during instruction decode when virt is enabled. However in some situations, illegal instruction exception can be raised due to state of CPU. One such situation is implementing branch tracking. [1] An indirect branch if doesn't land on a landing pad instruction, then cpu must raise an illegal instruction exception. Implementation would raise such expcetion due to missing landing pad inst and not due to decode. Thus DisasContext must have `virt_inst_excp` initialized to false during DisasContxt initialization for TB.
