Skipping a jal instruction in riscv64 baremetal emulation
Description of problem:
The binary contains an illegal instruction after a jal. Normally the jal should be taken but the illegal instructi[aia_tests2.elf](/uploads/b8b646b01d7bcc15b51c36ddbffacac7/aia_tests2.elf)on next to the jal is executed generating and illegal instruction exception:
```
0x80006070: 00200513 addi a0,zero,2
0x80006074: 89cff0ef jal ra,-3940 # 0x80005110
----------------
IN: _Z15int_switch_modehh
0x80006078: 0000 illegal
----------------
IN: mtvec_table
0x8000e600: 64d0406f j 20044 # 0x8001344c
```
Steps to reproduce:
