Macro safe_arch::shr_imm_i32_m128i

macro_rules! shr_imm_i32_m128i {
    ($a:expr, $imm:expr) => { ... };
}

Shifts all i32 lanes right by an immediate.

New bits are the sign bit.

let a = m128i::from([1, 2, -3, -4]);
let c: [i32; 4] = shr_imm_i32_m128i!(a, 3).into();
assert_eq!(c, [1 >> 3, 2 >> 3, -3 >> 3, -4 >> 3]);
