aeubanks added a comment. Some backends don't run SimplifyCFG, e.g. X86. I believe the pass was originally created specifically for X86 (the header has some X86 examples) and may or may not extend to other targets (I'm not very familiar with the pass itself).
I'm not opposed to landing this and seeing who complains, but if somebody does, we can make this pass X86-specific by adding it to X86TargetMachine::registerPassBuilderCallbacks() (which doesn't exist yet).
