Function i32x4_relaxed_trunc_f32x4
#[target_feature(enable = "relaxed-simd")]
pub fn i32x4_relaxed_trunc_f32x4(a: v128) -> v128A relaxed version of i32x4_trunc_sat_f32x4(a) converts the f32 lanes
of a to signed 32-bit integers.
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.
