[PATCH] D35073: [RegisterCoalescer] Fix for subrange join unreachable

[Tim Renouf via Phabricator via llvm-commits]

tpr added a comment.

I have confirmed that Krzysztof's fix that I put in the comment above does not fix the test case here, and it does not fix 179 of the 209 shaders with the problem that I found in a couple of our big apps.

So I think we need to go with David's fix.
