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)]`.

This directory contains test cases for the instcombine transformation. The dated tests are actual bug tests, whereas the named tests are used to test for features that the this pass should be capable of performing.
