[InstSimplify] with logical ops: (X & Y) == -1 ? X : -1 --> -1
Use simplifySelectWithICmpEq to handle the implied equalities from the icmp-and,
then both of ICMP_NE and ICMP_EQ will be addressed including vector type.
(X & Y) == -1 ? X : -1 --> -1 (commuted 2 ways)
(X & Y) != -1 ? -1 : X --> -1 (commuted 2 ways)
This is a supplement to the icmp-or scenario on D148986.
