This patch add support for the missing transformation of (x | y) == x ->

The transformation for (x & y) == x case already exists in

Hi
This patch add support for the missing transformation of (x | y) == x ->
(y & ~x) == 0.
The transformation for (x & y) == x case already exists in
simplify-rtx.c since 2014 as of r218503 and this patch only adds a
couple of extra patterns for the IOR case.
