Currently, the assembly functions for restoring register state have been direct implementations of the Registers_*::jumpto() method (contrary to the functions for saving register state, which are implementations of the extern C function __unw_getcontext). This has included having the assembly function name match the C++ mangling of that method name (and having the function match the C++ member function calling convention). To simplify the interface of the assembly implementations, make the functions have C calling conventions and name mangling. This fixes building the library in with a MSVC C++ ABI with clang-cl, which uses a significantly different method name mangling scheme. (The library might not be of much use as C++ exception unwinder in such an environment, but the libunwind.h interface for stepwise unwinding still is usable, as is the _Unwind_Backtrace function.)
