a72b31c79e This is some groundwork for filtering the language Exception
breakpoints, for instance on the class of the thrown object.

This change doesn't actually make that work, the part where we
extract the thrown object type from the throw site isn't done yet.

This provides a general programmatic "precondition" that you can add
to breakpoints to give them the ability to do filtering on the LLDB
side before we pass the stop on to the user-provided conditions & 
callbacks.

f0c5aeb690 This patch implements several improvements to the
module-loading support for the expression parser.

- It adds support for auto-loading modules referred
  to by a compile unit.  These references are
  currently in the form of empty translation units.
  This functionality is gated by the setting

  target.auto-import-clang-modules (boolean) = false

- It improves and corrects support for loading
  macros from modules, currently by textually
  pasting all #defines into the user's expression.
  The improvements center around including only those
  modules that are relevant to the current context -
  hand-loaded modules and the modules that are imported
  from the current compile unit.

- It adds an "opt-in" mechanism for all of this
  functionality.  Modules have to be explicitly
  imported (via @import) or auto-loaded (by enabling
  the above setting) to enable any of this
  functionality.

It also adds support to the compile unit and symbol
file code to deal with empty translation units that
indicate module imports, and plumbs this through to
the CompileUnit interface.

Finally, it makes the following changes to the test
suite:

- It adds a testcase that verifies that modules are
  automatically loaded when the appropriate setting
  is enabled (lang/objc/modules-auto-import); and

- It modifies lanb/objc/modules-incomplete to test
  the case where a module #undefs something that is
  #defined in another module.

ede3193bbd Add a "force_kill" arg to Process::Destroy(). This is needed after
the changes in r233255/r233258.  Normally if lldb attaches to
a running process, when we call Process::Destroy, we want to detach
from the process.  If lldb launched the process itself, ::Destroy
should kill it.

However, if we attach to a process and the driver calls SBProcess::Kill()
(which calls Destroy), we need to kill it even if we didn't launch it
originally.

The force_kill param allows for the SBProcess::Kill method to force the
behavior of Destroy.

ab745c2ad8 Fix stepping a virtual thread when the python operating system was enabled.
The OperatingSystem plug-ins allow code to detect threads in memory and then say "memory thread 0x11111" is backed by the actual thread 1. 

You can then single step these virtual threads. A problem arose when thread specific breakpoints were used during thread plans where we would say "set a breakpoint on thread 0x11111" and we would hit the breakpoint on the real thread 1 and the thread IDs wouldn't match and we would get rid of the "stopped at breakpoint" stop info due to this mismatch. Code was added to ensure these events get forwarded and thus allow single stepping a memory thread to work correctly.

Added a test case for this as well.

48b475cbaa Fix warnings generated by clang-cl.
There were a couple of real bugs here regarding error checking and
signed/unsigned comparisons, but mostly these were just noise.

There was one class of bugs fixed here which is particularly
annoying, dealing with MSVC's non-standard behavior regarding
the underlying type of enums.  See the comment in
lldb-enumerations.h for details.  In short, from now on please use
FLAGS_ENUM and FLAGS_ANONYMOUS_ENUM when defining enums which
contain values larger than can fit into a signed integer.

c00ca313fd Fix a crasher that could happen when you run LLDB and evaluate an expression where the objective C runtime registers a helper function, and also have an Objective C or C++ exception breakpoint. When shutting down the process in Process::Finalize() we clear a STL collection class and that causes objects to be destroyed that could re-enter Process and cause it to try to iterate over that same collection class that is being destroyed.
Guard against this by setting a new "m_finalizing" flag that lets us know we are in the process of finalizing.

e6d213a84a Fix a race condition in Target::Launch
When no hijack listener is set up, the global event listener will
try to pull events off the queue, racing with the event thread.
By always forcing a hijack listener, even when one was not given,
we guarantee that the listener always gets all events.

This was causing problems in synchronous mode with the process
stop event sometimes never being picked up and causing the debugger
to hang while processing a .lldbinit file.

0783ab9a7f [DWARF] If linkages names are missing, use decl context to get qualified names.
Summary:
This commit adds this alternate route only when parsing variable dies
corresponding to global or static variables. The motivation for this is that GCC
does not emit linkage names for functions and variables declared/defined in
anonymous namespaces. Having this alternate route fixes one part of
TestNamespace which fails when the test case is compiled with GCC.

An alternate route to get fully qualified names of functions whose linkage names
are missing will be added with a followup change. With that, the other failing
part of TestNamespace will also be fixed.

Test Plan: dotest.py -C gcc -p TestNamespace

on android the dynamic linker only reports the name of the SO file and

0641ca1a2d Remove ScriptInterpreterObject.
This removes ScriptInterpreterObject from the codebase completely.
Places that used to rely on ScriptInterpreterObject now use
StructuredData::Object and its derived classes.  To support this,
a new type of StructuredData object is introduced, called
StructuredData::Generic, which stores a void*.  Internally within
the python library, StructuredPythonObject subclasses this
StructuredData::Generic class so that it can addref and decref
the python object on construction and destruction.

Additionally, all of the classes in PythonDataObjects.h such
as PythonList, PythonDictionary, etc now provide a method to
create an instance of the corresponding StructuredData type.  For
example, there is PythonDictionary::CreateStructuredDictionary.
To eliminate dependencies on PythonDataObjects for external
callers, all ScriptInterpreter methods now return only
StructuredData classes

The rest of the changes in this CL are focused on fixing up
users of PythonDataObjects classes to use the new StructuredData
classes.

3f5df53fde Fix ProcessIO test failures
Summary:
There was a race condition regarding the output of the inferior process. The reading of the
output is performed on a separate thread, and there was no guarantee that the output will get
eventually consumed. Because of that, it was happening that calling Process::GetSTDOUT was not
returning anything even though the process was terminated and would definitely not produce any
further output. This was usually happening only under very heavy system load, but it can be
reproduced by placing an usleep in the stdio thread (Process::STDIOReadThreadBytesReceived).

This patch addresses this by adding synchronization capabilities to the Communication thread.
After calling Communication::SynchronizeWithReadThread one can be sure that all pending input has
been processed by the read thread. This function is then called after every public event which
stops the process to obtain the entire process output.

Test Plan: TestProcessIO.py should now succeed every time instead of flaking in and out.

78521ef545 Fix race condition with -o "process launch" on linux
Summary:
starting a debug session on linux with -o "process launch" lldb parameter was failing since
Target::Launch (in sychronous mode) is expecting to be able to receive public process events.
However, PlatformLinux did not set up event hijacking on process launch, which caused these
events to be processed elsewhere and left Target::Launch hanging. This patch enables event
interception in PlatformLinux (which was commented out).

Upon enabling event interception, I noticed an issue, which I traced back to the inconsistent
state of public run lock, which remained false even though public and private process states were
"stopped". I addressed this by making sure the run lock is "stopped" upon exit from
WaitForProcessToStop (which already had similar provisions for other return paths).

Test Plan: This should fix the intermittent TestFormats failure we have been experiencing on Linux.
