While building one of the internal benchmark here, compiler started aborting
with following message from svn r249211.

Instruction does not dominate all uses!
  %55 = add i32 %z.0134, %54
  %z.0134 = phi i32 [ 0, %if.end ], [ %55, %for.inc.28 ]
fatal error: error in backend: Broken function found, compilation aborted!
clang: error: clang frontend command failed with exit code 70 (use -v to see
invocation)
clang version 3.8.0 (trunk 249210) (llvm/trunk 249211)
Target: x86_64-unknown-linux-gnu

I shall try to come up with reproducible test case.
