[OptimizeInstructions] Canonicalize relational ops near min/max values (#4282)
A continuation of #4272.
```
(signed)x < s_min + 1 ==> x == s_min
(signed)x >= s_min + 1 ==> x != s_min
(signed)x > s_max - 1 ==> x == s_max
(signed)x <= s_max - 1 ==> x != s_max
(unsigned)x <= u_max - 1 ==> x != u_max
(unsigned)x > u_max - 1 ==> x == u_max
```
