In Dex register maps, instead of\n  storing the actual location of a (live) Dex register,\n  store the index of the location catalog entry containing\n  that Dex register location.\n- Adjust art::StackMapStream,\n  art::CheckReferenceMapVisitor::CheckOptimizedMethod,\n  art::StackVisitor::GetVRegFromOptimizedCode, and\n  art::StackVisitor::SetVRegFromOptimizedCode.\n- Add LoadBits and StoreBits methods to art::MemoryRegion\n  to load and store a block of adjacent bits in a memory\n  region.\n- Update compiler/optimizing/stack_map_test.cc.\n- Remove the default value for parameter EmptyFn of\n  art::HashMap.  This default value did not seem to make\n  sense, as it would create an \"empty function\" for type Key\n  by default, whereas art::HashMap expects an \"empty\n  function\" for type std::pair\u003cKey, Value\u003e.\n\nChange-Id: Id9e49d7756c253ce41c36630cd832208d06c2e28\n"
