Greg Clayton fc75303acb Avoid infinite loops in stack backtraces and renamed: ...

bool RegisterContextLLDB::GetPC (addr_t& pc);

to:
    bool RegisterContextLLDB::ReadPC (addr_t& pc);
    
To avoid confusion with the GetPC() function that is part of the 
lldb_private::RegisterContext:

    uint64_t RegisterContext::GetPC (uint64_t fail_value);
    
Bad things could happen if the two got intermixed and the wrong one got
called.

Fixed inifinite loop detection by watching for two frames where the
RegisterContextLLDB::CursorSP contains the same start_pc and cfa.
