<pre>Never mind, this was apparently fixed by <a href="https://reviews.llvm.org/rL342397">https://reviews.llvm.org/rL342397</a>,
which was in turn a fixed version of <a href="https://reviews.llvm.org/rL342183">https://reviews.llvm.org/rL342183</a>:

[DAGCombine] Fix crash when store merging created an extract_subvector with
invalid index.
Differential Revision: <a href="https://reviews.llvm.org/D51831">https://reviews.llvm.org/D51831</a>
------------------------------------------------------------------------
Still, 7.0.0 and 7.0.1 still have this issue, so maybe it would be nice to
backport r342397.</pre>
