Non-trapping float-to-int

Instead of trapping on overflow or NaN, these instructions clamp to min/max and convert NaN to 0.

(module
  (func (export "sat") (param $x f32) (result i32)
    (i32.trunc_sat_f32_s (local.get $x)))
)

All variants: i32.trunc_sat_f32_s/u, i32.trunc_sat_f64_s/u, i64.trunc_sat_f32_s/u, i64.trunc_sat_f64_s/u.
