Illegal instruction trap is generated if CPU doesn't support AVX

[pepyakin]

Looks like it tries to execute vpslldq instruction which requires AVX{1,2}, but my machine doesn't have it.

->  0x5555562028a1 <+129>: vpslldq $0x4, %xmm1, %xmm3        ; xmm3 = zero,zero,zero,zero,xmm1[0,1,2,3,4,5,6,7,8,9,10,11]
    0x5555562028a6 <+134>: pxor   %xmm3, %xmm1
    0x5555562028aa <+138>: vpslldq $0x4, %xmm1, %xmm3        ; xmm3 = zero,zero,zero,zero,xmm1[0,1,2,3,4,5,6,7,8,9,10,11]
    0x5555562028af <+143>: pxor   %xmm3, %xmm1

Might moving to RustCrypto help?
