[RFC] jump threading on std::pair<int, bool>
...ciate it if I could have any suggestions on how we can
optimization such cases.
I am planning to enhance InstCombine pass to eliminate these additional
instructions before jump threading rather than enhancing SROA or jump
threading.
Here is LLVM IR generated for above C code.
