Only the mov scenario was measured, when it comes to avx512 embedded
broadcast it's 1 avx512 embedded broadcast instruction vs at least 3
instructions: mov + broadcast + op. I'm not sure which is better?

take pr87767 for example.
vpaddd .LC1(%rip){1to16}, %zmm0, %zmm0
.LC1:
        .long   3

vs

movl 3, %eax
vpbroadcastd %eax, %zmm1
vpaddd %zmm1, %zmm0, %zmm0

As mentioned above, if avx512 embedded broadcast is better, this could
prevent potential optimization where mode is v8si mode, but broadcast
as qimode.
