Change the GDBRemoteRegisterContext::AddRegister function to take
its RegisterInfo argument by value instead of using a reference -
it will modify the object and modifying the contents of the 
g_register_infos table in GDBRemoteRegisterContext.cpp can cause a
crash the next time we step through it.
