Function i32x4_relaxed_trunc_f64x2_zero

#[target_feature(enable = "relaxed-simd")]
pub fn i32x4_relaxed_trunc_f64x2_zero(a: v128) -> v128

A relaxed version of i32x4_trunc_sat_f64x2_zero(a) converts the f64 lanes of a to signed 32-bit integers and the upper two lanes are zero.

Values which don't fit in 32-bit integers or are NaN may have the same result as i32x4_trunc_sat_f32x4 or may return i32::MIN.
