[llvm] [InstCombine] fold "icmp eq (X + (V - 1)) & -V, X" to "icmp eq (and X, V - 1), 0" (#152851)

This fold optimizes 

```llvm
define i1 @src(i32 %num, i32 %val) {
  %mask = add i32 %val, -1
  %neg = sub nsw i32 0, %val

  %num.biased = add i32 %num, %mask
  %_2.sroa.0.0 = and i32 %num.biased, %neg
  %_0 = icmp eq i32 %_2.sroa.0.0, %num
  ret i1 %_0
}
```
to
```llvm
define i1 @tgt(i32 %num, i32 %val) {
  %mask = add i32 %val, -1
  %tmp = and i32 %num, %mask
  %ret = icmp eq i32 %tmp, 0
  ret i1 %ret
}
```

For power-of-two `val`.

Observed in real life for following code

```rust
pub fn is_aligned(num: usize) -> bool {
    num.next_multiple_of(1 << 12) == num
}
```
which verifies that num is aligned to 4096.
