Since C++11, the C++ standard has a forward progress guarantee [intro.progress], so all such functions must have the `mustprogress` requirement. In addition, from C11 and onwards, loops without a non-zero constant conditional or no conditional are also required to make progress (C11 6.8.5p6). This patch implements these attribute deductions so they can be used by the optimization passes. Differential Revision: https://reviews.llvm.org/D86841
