Sanjoy Das 7516192a71 Revert a couple of InstCombine/Guard checkins 
This change reverts:

r293061: "[InstCombine] Canonicalize guards for NOT OR condition"
r293058: "[InstCombine] Canonicalize guards for AND condition"

They miscompile cases like:

```
declare void @llvm.experimental.guard(i1, ...)

define void @test_guard_not_or(i1 %A, i1 %B) {
  %C = or i1 %A, %B
  %D = xor i1 %C, true
  call void(i1, ...) @llvm.experimental.guard(i1 %D, i32 20, i32 30)[ "deopt"() ]
  ret void
}
```

because they do transfer the `i32 20, i32 30` parameters to newly
created guard instructions.
