Summary: Many functions (around 600) in the HHVM binary are simply a single unconditional jump instruction to another function. These can be trivially optimized by modifying the call sites to directly call the branch target instead (because it also happens with more than one jump in sequence, we do it iteratively). This diff also adds a very simple analysis/optimization pass system in which this pass is the first one to be implemented. A follow-up to this could be to move the current optimizations to other passes. (cherry picked from FBD3211138)
