Revert "[X86] Use X86ISD::SUB instead of X86ISD::CMP in some places."
This reverts commit 8413116bf10402eef12f556cb9d80b08faeb9890.
this seems to be causing crashes while compiling ncurses.
```
$ ./bin/llc bugpoint-reduced-simplified.ll
LLVM ERROR: Cannot emit physreg copy instruction
```
Here are the crashers: https://gist.github.com/kadircet/918f5bb97a2afe048cb875490edba46e
executing with an llc compiled at 904d54de9ba9f71e937b24e04ad5941281cd50b7 works fine.
