  gcc 4.3.4 does not include "immintrin.h", and will post below error:
    lib/librte_sched/rte_sched.c:56:23: error:
    immintrin.h: No such file or directory

This compiler issue is fixed with rte_vect.h

There is another issue, need SSE2 support

Fixes: 42ec27a0178a ("sched: enable SSE optimizations in config")

Signed-off-by: Michael Qiu <michael.qiu@intel.com>

v3 --> v2:
	reformat commit log
	move rte_vect.h inside RTE_SCHED_VECTOR

v2 --> v1:
	include header file rte_vect.h instead of gcc version check
	change __AVX__ to __SSE2__ since all vector function are SSE2 related
