add testscases for some factorization of distributive operations
Add some testcases for factorizations of:
(x * z) + (y * z) --> (x + y) * z
(x | z) & (y | z) --> (x & y) | z
(x & z) | (y & z) --> (x | y) & z
(x & z) ^ (y & z) --> (x ^ y) & z
and
(x << s) | (y << s) --> ((x | y) << s)
and same for &, ^, LSR and ASR.
