vppinfra: clib_memcpy optimization
This patch allows copiler to select which SIMD instructions will be used for copying 16 and 32 byte block. Immediate effect of this change will occur in avx2 variants of graph node functions. So far 128 byte registers were used even in code optimized for avx2 due to macro nature of clib_memcpy. With this patch gcc should pick 256 byte registers in such cases.
