This proposal introduces 8 new instructions:

- `i32.trunc_s:sat/f32`
- `i32.trunc_u:sat/f32`
- `i32.trunc_s:sat/f64`
- `i32.trunc_u:sat/f64`
- `i64.trunc_s:sat/f32`
- `i64.trunc_u:sat/f32`
- `i64.trunc_s:sat/f64`
- `i64.trunc_u:sat/f64`
- `i32.trunc_sat_f32_s`
- `i32.trunc_sat_f32_u`
- `i32.trunc_sat_f64_s`
- `i32.trunc_sat_f64_u`
- `i64.trunc_sat_f32_s`
- `i64.trunc_sat_f32_u`
- `i64.trunc_sat_f64_s`
- `i64.trunc_sat_f64_u`

The semantics are the same as the corresponding non-`:sat` instructions, except:
- Instead of trapping on positive or negative overflow, they return the maximum
