When rte_lpm.h is used on x86, -O0 option (no optimization at all)
given to gcc causes a compile error like this:
error: the last argument must be an 8-bit immediate
i24 = _mm_srli_si128(i24, sizeof(uint64_t));
-O0 option is useful for debugging and code coverage measurement, but
this error prevents DPDK programs from building. This patch replaces
"sizeof(uint64_t)" with a constant literal "8" to work around the issue.
The issue occurs on gcc/g++ versions from 4.8 to 5.
