#[target_feature(enable = "sha")]
pub fn _mm_sha1rnds4_epu32(a: __m128i, b: __m128i, FUNC: i32) -> __m128iPerforms four rounds of SHA1 operation using an initial SHA1 state (A,B,C,D)
from a and some pre-computed sum of the next 4 round message values
(unsigned 32-bit integers), and state variable E from b, and return the
updated SHA1 state (A,B,C,D). FUNC contains the logic functions and round
constants.
