user space programs. The core file support is implemented by making a process plug-in that will dress up the threads and stack frames by using the core file memory. Added many default implementations for the lldb_private::Process functions so that plug-ins like the ProcessMachCore don't need to override many many functions only to have to return an error. Added new virtual functions to the ObjectFile class for extracting the frozen thread states that might be stored in object files. The default implementations return no thread information, but any platforms that support core files that contain frozen thread states (like mach-o) can make a module using the core file and then extract the information. The object files can enumerate the threads and also provide the register state for each thread. Since each object file knows how the thread registers are stored, they are responsible for creating a suitable register context that can be used by the core file threads. Changed the process CreateInstace callbacks to return a shared pointer and to also take an "const FileSpec *core_file" parameter to allow for core file support. This will also allow for lldb_private::Process subclasses to be made that could load crash logs. This should be possible on darwin where the crash logs contain all of the stack frames for all of the threads, yet the crash logs only contain the registers for the crashed thrad. It should also allow some variables to be viewed for the thread that crashed. llvm-svn: 150154
