rGd4bfce552110: [Attributor] Utilize the InstSimplify interface to simplify instructions
Summary

When we simplify at least one operand in the Attributor simplification
we can use the InstSimplify to work on the simplified operands. This
allows us to avoid duplication of the logic.

Depends on D106189
