## Checks that llvm-bolt is able to read data generated by perf2bolt, update the
## CFG edges accordingly with absolute number of branches and mispredictions,
## infer fallthrough branch info and reorder basic blocks using a greedy
## heuristic, or find the optimal solution if the function is small enough.
## Also checks that llvm-bolt disassembler and CFG builder is working properly.
