Matthew Simpson 06f1a4b52b Reapply "[LV] Extend trunc optimization to all IVs with constant integer steps" ...

This reapplies commit r294967 with a fix for the execution time regressions
caught by the clang-cmake-aarch64-quick bot. We now extend the truncate
optimization to non-primary induction variables only if the truncate isn't
already free.
