[Optimize Instructions] Simplify sign extentions (#4004)
requiring sign-extension:
```
i64(x) << 56 >> 56 ==> i64.extend8_s(x)
i64(x) << 48 >> 48 ==> i64.extend16_s(x)
i64(x) << 32 >> 32 ==> i64.extend32_s(x)
i64.extend_i32_s(i32.wrap_i64(x)) ==> i64.extend32_s(x)
```
general:
```
i32.wrap_i64(i64.extend_i32_s(x)) ==> x
i32.wrap_i64(i64.extend_i32_u(x)) ==> x
```
