[Optimize Instructions] Simplify zero/sign extentions (special case) (#4009)
For signed or unsigned extension to 64-bits after lowering from partially filled 64-bit arguments:
```rust
i64.extend_i32_u(i32.wrap_i64(x)) => x // where maxBits(x) <= 32
i64.extend_i32_s(i32.wrap_i64(x)) => x // where maxBits(x) <= 31
```
