Extended Description

Sorry about the huge regression range. I'll try to narrow it down.

Assertion failed: (index < Probs.size() && "Not a current successor!"), function getProbabilityIterator, file /b/build/slave/mac_upload_clang/build/src/third_party/llvm/lib/CodeGen/MachineBasicBlock.cpp, line 1184. Stack dump:

Sounds like this was fixed by reverting.
