vppinfra: add CLIB_ASSUME() macro
This macro privides a way to tell compiler that it is safe to assume that specified expression is true so it can optimize code accordingly. i.e. CLIB_ASSUME (n < 3); while (n) { /* ... */ } Will tell compiler that n is never going to be >= 3 so instead of creating loop it will just unroll loop 2 times.
