sys: tell compiler about impossible aliasing in dlist APIs The compiler was inserting additional redundant loads in many `sys_dlist_*` APIs, in case writes aliased with previous reads. However, these additional reads are unnecessary, as the only cases where the aliasing would matter would be a violation of the `dlist` API contract (e.g. if node->next == node but node->prev != node). This is decidedly a micro-optimization. Signed-off-by: James Harris <james.harris@intel.com>
