test for a variety of new transformations:
...
* A & ~A == 0
* A / (2^c) == A >> c if unsigned
* 0 / A == 0
* 1.0 * A == A
* A * (2^c) == A << c
* A ^ ~A == -1
* A | ~A == -1
* 0 % X = 0
* A % (2^c) == A & (c-1) if unsigned
* A - (A & B) == A & ~B
* -1 - A == ~A

These tests should not run -dce pass to cleanup instcombine.
