<pre>Over the last year, the LoopInterchange pass has seen some improvements fixing
all known/reported bugs.
Currently the pass is still quite limited in the types of loops is supports and
I think we should get a few improvements in before we consider enabling it by
default:
* Add support for reductions (PR30472), <a href="https://reviews.llvm.org/D43245">https://reviews.llvm.org/D43245</a>
* Use cache-based cost model (<a href="https://reviews.llvm.org/D35210">https://reviews.llvm.org/D35210</a>)</pre>
