c2b935904a poly1305/asm/poly1305-x86_64.pl: add poly1305_blocks_vpmadd52_4x. 
As hinted by its name new subroutine processes 4 input blocks in
parallel. It still operates on 256-bit registers and is just
another step toward full-blown AVX512IFMA procedure.

73e8a5c826 poly1305/asm/poly1305-x86_64.pl: switch to vpermdd in table expansion. 
Effectively it's minor size optimization, 5-6% per affected subroutine.

c1e1fc500d poly1305/asm/poly1305-x86_64.pl: optimize AVX512 code path. 
On pre-Skylake best optimization strategy was balancing port-specific
instructions, while on Skylake minimizing the sheer amount appears
more sensible.
