Hi Yonghong,

Looks good to me, thanks!
Before landing this, could you please adjust tests a little bit more?

- Extend `assembler-disassembler-v4.s` with signed `div` and `mod`, e.g.:

  // CHECK: 3f 31 01 00 00 00 00 00	r1 s/= r3
  // CHECK: 9f 42 01 00 00 00 00 00	r2 s%= r4
  r1 s/= r3
  r2 s%= r4
  
  // CHECK: 3c 31 01 00 00 00 00 00	w1 s/= w3
  // CHECK: 9c 42 01 00 00 00 00 00	w2 s%= w4
  w1 s/= w3
  w2 s%= w4

- For `gotol` add a test case which tries each possibility in `BPFMIPreEmitPeephole::adjustBranch()`
