Fix treatment of ARM unallocated hint instructions. The reference manual defines only 5 permitted values for the immediate field of the "hint" instruction: 1. nop (imm == 0) 2. yield (imm == 1) 3. wfe (imm == 2) 4. wfi (imm == 3) 5. sev (imm == 4) Therefore, restrict the permitted values for the "hint" instruction to 0 through 4.
