[Attributor] Extend the AAValueSimplify compare simplification logic

Browse Source 
We first simplify the operands of a compare and then reason on the
simplified versions, e.g., with AANonNull.

This does improve the simplification capabilities but also fixes a
potential problem that has not yet been observed by simplifying the
operands first.
