@mkazantsev, could you help to take a look at the latest version?
@nikic expressed his concern on compile time, then I sent out this version to improve compile time. But @nikic didn't response for several weeks.
The change is the use of a new variable AdditionalWorkSet for tracking BBs contain dead load, so we can process these BBs from AdditionalWorkSet at the end of each iteration, and avoid an extra iteration on the whole function.
