<pre>Thank you for posting the tests. I reduced the 1st example in:
<a href="https://reviews.llvm.org/rL373913">https://reviews.llvm.org/rL373913</a>
And the change that caused the regression was reverted:
<a href="https://reviews.llvm.org/rL373882">https://reviews.llvm.org/rL373882</a>
So I think we can close this report. The patch that caused the bug is modified
and up for re-review at:
<a href="https://reviews.llvm.org/D67841">https://reviews.llvm.org/D67841</a></pre>
