Sean Callanan d2a507a6e6 Modified the expression parser to only try to
write to registers if they were modified in the
expression.  This eliminates spurious errors if
the register can't be written to but the
expression didn't write to it anyway.

Also improved error handling for the materializer
to make "couldn't materialize struct" errors more
informative.

Greg Clayton 3deb0e7ca5 Revert the ELF core file support until a few things can be worked out:
RegisterContextCoreLinux_x86_64 inherits from RegisterContextLinux_x86_64 which inherits from RegisterContext_x86_64 which uses has:

   ProcessMonitor &GetMonitor();

This register context used by the core file can't use this since the process plug-in will be ProcessElfCore and the implementation of GetMonitor() does:

ProcessMonitor &
RegisterContext_x86_64::GetMonitor()
{
   ProcessSP base = CalculateProcess();
   ProcessPOSIX *process = static_cast<ProcessPOSIX*>(base.get());
   return process->GetMonitor();
}

ProcessELFCore doesn't, nor should it inherit from ProcessPOSIX and any call to GetMonitor() will fail for ELF core files.

Suggested cleanups:
- Make a register context class that is a base class that doesn't have any reading smarts, then make one that uses ProcessPOSIX and the has the GetMonitor() call, and one that gets its data straight from the core file.

Greg Clayton 2540a8a7bc Fixed GetModuleSpecifications() to work better overall:
- MachO files now correctly extract the UUID all the time
- More file size and offset verification done for universal mach-o files to watch for truncated files
- ObjectContainerBSDArchive now supports enumerating all objects in BSD archives (.a files)
- lldb_private::Module() can not be properly constructed using a ModuleSpec for a .o file in a .a file
- The BSD archive plug-in shares its cache for GetModuleSpecifications() and the create callback
- Improved printing for ModuleSpec objects

Jim Ingham f1715ab270 Get debugserver to call task_set_state to prime the control registers so that watchpoints
take for threads created while the program is running.  Remove the testcase skips from TestConcurrentEvents.py,
since they all pass now, and fix TestWatchpointMultipleThreads.py - which should have caught this problem -
so it doesn't artificially break on new thread creation before the watchpoint triggers.

Greg Clayton 57ee306789 Huge change to clean up types.
A long time ago we start with clang types that were created by the symbol files and there were many functions in lldb_private::ClangASTContext that helped. Later we create ClangASTType which contains a clang::ASTContext and an opauque QualType, but we didn't switch over to fully using it. There were a lot of places where we would pass around a raw clang_type_t and also pass along a clang::ASTContext separately. This left room for error.

This checkin change all type code over to use ClangASTType everywhere and I cleaned up the interfaces quite a bit. Any code that was in ClangASTContext that was type related, was moved over into ClangASTType. All code that used these types was switched over to use all of the new goodness.

Daniel Malea 7df860a629 Improve TestConcurrentEvents.py
- code cleanup, improved reporting when failures take place
- ensure known thread is interrupted by using pthread_kill() instead of kill() in the signal worker thread
- above should avoid llvm.org/pr16567 on Mac OS X (though kill() could still cause threads to pop out of existance temporarily)
- added an additional check that all threads have exited after worker threads are all join()ed
- logged llvm.org/pr16603 for the new Linux bug discovered

Greg Clayton 3046e66830 Cleanup on the unified section list changes. Main changes are:
- ObjectFile::GetSymtab() and ObjectFile::ClearSymtab() no longer takes any flags
- Module coordinates with the object files and contain a unified section list so that object file and symbol file can share sections when they need to, yet contain their own sections.

Other cleanups:
- Fixed Symbol::GetByteSize() to not have the symbol table compute the byte sizes on the fly
- Modified the ObjectFileMachO class to compute symbol sizes all at once efficiently
- Modified the Symtab class to store a file address lookup table for more efficient lookups
- Removed Section::Finalize() and SectionList::Finalize() as they did nothing
- Improved performance of the detection of symbol files that have debug maps by excluding stripped files and core files, debug files, object files and stubs
- Added the ability to tell if an ObjectFile has been stripped with ObjectFile::IsStripped() (used this for the above performance improvement)

Daniel Malea b3d41a278b Add TestConcurrentEvents test for LLDB's handling of inferior threads
- Test verifies LLDB's handling of inferiors with threads that: hit breakpoints,
  modfiy variables that have watchpoints set, generate user signals, and crash.
- Add a few "stress tests" (with ~100 threads) -- run these with "-l" dotest.py
  flag.
- Fix stop_reason_to_str helper in lldbutil to handle eStopReasonThreadExited.
- Add sort_stopped_threads helper to lldbutil to separate thread lists based
  on stop reason.

Greg Clayton 226cce2511 Added a way to extract the module specifications from a file. A module specification is information that is required to describe a module (executable, shared library, object file, ect). This information includes host path, platform path (remote path), symbol file path, UUID, object name (for objects in .a files for example you could have an object name of "foo.o"), and target triple. Module specification can be used to create a module, or used to add a module to a target. A list of module specifications can be used to enumerate objects in container objects (like universal mach files and BSD archive files).
There are two new classes:

lldb::SBModuleSpec
lldb::SBModuleSpecList

The SBModuleSpec wraps up a lldb_private::ModuleSpec, and SBModuleSpecList wraps up a lldb_private::ModuleSpecList.
