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.
Type: improvement
