pub unsafe fn _mm_sha1rnds4_epu32(a: __m128i, b: __m128i, func: i32) -> __m128i
Performs four rounds of SHA1 operation using an initial SHA1 state (A,B,C,D)
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
