Use crc32 wrapper (VPP-1086)
This allows arm platforms to also take advantage of crc32 hardware acceleration. * add a wrapper for crc32_u64. It's the only one really used. Using it instead of a call to clib_crc32c() eases building symmetrical hash functions. * replace #ifdef on SSE4 by a test on clib_crc32c_uses_intrinsics. Note: keep the test on i386 * fix typo in lb test log Change-Id: I03a0897b70f6c1717e6901d93cf0fe024d5facb5 Signed-off-by: Gabriel Ganne <gabriel.ganne@enea.com>
