[InstCombine] Add mul with negated power of 2 constant to canEvaluateShifted.
If we are right shifting a multiply by a negated power of 2 where
the power of 2 is the same as the shift amount, we can replace with
a negate followed by an And.
New tests have not been committed yet but the patch shows the diffs.
Let me know if you want any changes or additional tests.
