Dinesh Dwivedi 8317509052 Refactored and updated SimplifyUsingDistributiveLaws() to ...

* Find factorization opportunities using identity values.
 * Find factorization opportunities by treating shl(X, C) as mul (X, shl(C))
 * Keep NSW flag while simplifying instruction using factorization.

This fixes PR19263.
