<summary>Changes</summary>
This extends `opitimizeCompareInstr` to re-use previous CCMP results if the
previous comparison was with an immediates that was 1 bigger or smaller. Example:
```
CCMP x, 13, 2, 5
...
CCMP x, 12, 2, 5 ; can be removed if we change the SETg
SETg ... ; x > 12 changed to SETge (x >= 13) & remove the 2nd
CCMP
```
