cmd/exception: support RISC-V compressed instruction
Eliminating the C extension on application processors is under
discussion.
Support emitting a compressed instruction. This will lead to an
illegal instruction exception if the C extension is not implemented.
For testing build qemu-riscv64_defconfig with CONFIG_RISCV_ISA_C=n
and run with
qemu-system-riscv64 -M virt -bios u-boot -nographic -cpu rv64,c=false
=> exception compressed
Unhandled exception: Illegal instruction
