Protobuf uses `dynamic_cast` on polymorphic types which cannot be
inferred properly at compile-time, which can lead to unexpected behavior.
As a code safety measure, enable C++ RTTI for protobuf.
Updating Iterators to be compatible with C++17
The std::iterator class is being deprecated on MSVC++,
and currently if the compilation flag /std:c++latest
is used a warning is issued in this regard if any
iterators use the class as a base class.
If an external source file being compiled includes
the repeated_field.h header, the iterator clases
RepeatedPtrIterator and RepeatedPtrOverPtrsIterator
trigger the warning.
This change solves the warning and should avoid it in
the future when the default is to remove the class.

Correct various pre-processor defines for sparc64 and in mozjemalloc use the JS arm64 allocator on Linux/sparc64.
This corrects build problems opn Linux sparc64 and is in line with bugzilla bug #1275204.
