[llvm] r347917 - [DAGCombiner] narrow truncated binops

Hi Sanjay,
I've seen some instances of Clang going OOM, and it appears to cleanly
bisect to this revision. The affected builds are while building Clang
itself (FrontendAction, Sema, and a couple of others) targeting PPC with
ASAN (which uses -O1).
Unfortunately, since the reproduction requires running to OOM, reproducing
takes longer than I would like. I haven't been able to get a useful,
reduced example, but I am trying to get one (manually and via creduce). I'm
also trying to reproduce with a Clang built with a few different sanitizers
(although these are also a bit finicky, so no luck yet there, either.)
I'm not familiar with this area of LLVM, so the best fix I can offer is a
revert.
Could you advise on a fix? (If you don't have a timely fix in mind,
please let me know if you would like me to revert the revision for you.)
Thanks,
David Jones
