Hello, it seems that this patch is causing a compiler crash for us when building a 4.4 Linux kernel.
https://github.com/ClangBuiltLinux/linux/issues/930
It appears to cause a crash during inlining, though I just run `opt -inline <module before inlining from -O2>` I don't observe the crash.  I assume there's some analysis pass I need to run first?  `opt -instsimplify -inline` also didn't seem to work, though `opt -O2` does. See link above for steps to reproduce and most concise reproducer I could come up with.
