Hafiz Abid Qadeer 290ece8278 Fix a bug where global variable can be reported as local.
There was an error in ORing mask which is used for getting a list of variables.
Previously, these constants were unnamed, and possible it become the reason of this
bug. Also added test case for -stack-list-local and -stack-list_arguments.

Patch from Ilia K <ki.stfu@gmail.com>.

Jason Molenda e589e7e336 The lldb unwinder can now use the unwind information from the compact-unwind
section for x86_64 and i386 targets on Darwin systems.  Currently only the
compact unwind encoding for normal frame-using functions is supported but it
will be easy handle frameless functions when I have a bit more free time to
test it.  The LSDA and personality routines for functions are also retrieved
correctly for functions from the compact unwind section.

This new code is very fresh -- it passes the lldb testsuite and I've done
by-hand inspection of many functions and am getting correct behavior for all
of them.  There may need to be some bug fixing over the next couple weeks as
I exercise and test it further.  But I think it's fine right now so I'm
committing it.

Jim Ingham 33df7cd345 Add the ability to set breakpoints with conditions, commands, etc,
in the "dummy-target".  The dummy target breakpoints prime all future
targets.  Breakpoints set before any target is created (e.g. breakpoints
in ~/.lldbinit) automatically get set in the dummy target.  You can also
list, add & delete breakpoints from the dummy target using the "-D" flag,
which is supported by most of the breakpoint commands.

This removes a long-standing wart in lldb...

Sean Callanan ceeb74e606 Now that we get types from modules, we occasionally
encounter clang::ExternalASTSources that are not instances
of ClangExternalASTSourceCommon.  We used to blithely
assume that all are, and so we could use static_cast<>.
That's no longer the case, so we have to have these AST
sources register themselves.

Zachary Turner b3ff719b04 Manually call ModulesDidLoad when the executable is loaded.
This is a temporary workaround to get deferred breakpoint

executable module, and not in a shared library.

Zachary Turner c6a6653ebb Correctly shutdown when DoDestroy is called with an active exception.
Previously if we got a DoDestroy while stopped at a breakpoint, we
would detach and then say the process had exited.  This is completely
wrong, as it resulted in the python script incorrectly assuming that
the process had actually exited and trying to delete the image, when
in fact it had done no such thing.

The fix employed here is that when we get a DoDestroy, we do 3 steps:

1) initiate a termination sequence on the process
2) If we were stopped handling an exception of any kind, mask it and
   let the program resume, causing the program to see the termination
   request and exit on its own.
3) Let the program exit normally, and close all of our handles before
   returning control back to DoDestroy.

This fixes Bug 21722 and Bug 21723.

Realistically lldb isn't able to track register saves of any of

regs as unavailable when you're not on stack frame 0...
