Noah Goldstein 444383e0d0 [ValueTracking] Do more thorough non-zero check in isKnownToBePowerOfTwo when OrZero is no set. 
We can cover more cases by directly checking if the result is
known-nonzero for common patterns when they are missing `OrZero`.

This patch add `isKnownNonZero` checks for `shl`, `lshr`, `and`, and `mul`.
