arcfour: more optimized version for non-i386 architectures
* cipher/arcfour.c (ARCFOUR_context): Reorder members.
(do_encrypt_stream) [!__i386__]: Faster implementation for non-i386.
(do_arcfour_setkey): Avoid modulo operations.
--
Patch adds faster arcfour implementation for non-i386 architectures. New code
is not activated on i386 as performance would regress. This is because i386
does not have enough registers hold new variables.
Speed up on Intel i5-4570 (x86_64): 1.56x
Speed up on ARM Cortex-A8: 1.18x
