History

Andrew Trick c1482c669a Add simplifyLoopLatch to LoopRotate pass.

This folds a simple loop tail into a loop latch. It covers the common (in fortran) case of postincrement loops. It's a "free" way to expose this type of loop to downstream loop optimizations that bail out on non-canonical loops (getLoopLatch is a heavily used check).
