Sanjoy Das c86c162a58 Re-apply r245635, "[InstCombine] Transform A & (L - 1) u< L --> L != 0" ... The original checkin was buggy, this change has a fix. Original commit message: [InstCombine] Transform A & (L - 1) u< L --> L != 0 Summary: This transform is never a pessimization at the IR level (since it replaces an `icmp` with another), and has potentiall payoffs: 1. It may make the `icmp` fold away or become loop invariant. 2. It may make the `A & (L - 1)` computation dead. This shows up in Java, in range checks generated by array accesses of the form `a[i & (a.length - 1)]`.
