Also added a data formatter that presents them as structs if you use frame
variable to look at their contents. Now the blocks testcase works.

$(LLDB_PYTHON_TESTSUITE_CC) defaults to the just-built clang. Together
with changes to the zorg repo, this enables the Green Dragon LLDB OS X
Xcode-based builder to run the new TSAN LLDB tests.

This feature is controlled by an expression command option, a target property and the
SBExpressionOptions setting. FixIt's are only applied to UserExpressions, not UtilityFunctions,
those you have to get right when you make them.
This is just a first stage. At present the fixits are applied silently. The next step
is to tell the user about the applied fixit.

This patch adds ThreadSanitizer support into LLDB:
- Adding a new InstrumentationRuntime plugin, ThreadSanitizerRuntime, in the same way ASan is implemented.
- A breakpoint stops in `__tsan_on_report`, then we extract all sorts of information by evaluating an expression. We then populate this into StopReasonExtendedInfo.
- SBThread gets a new API, SBThread::GetStopReasonExtendedBacktraces(), which returns TSan’s backtraces in the form of regular SBThreads. Non-TSan stop reasons return an empty collection.
- Added some test cases.

We want to do a better job presenting errors that occur when evaluating
expressions. Key to this effort is getting away from a model where all
errors are spat out onto a stream where the client has to take or leave
all of them.
To this end, this patch adds a new class, DiagnosticManager, which
contains errors produced by the compiler or by LLDB as an expression
is created. The DiagnosticManager can dump itself to a log as well as
to a string. Clients will (in the future) be able to filter out the
errors they're interested in by ID or present subsets of these errors
to the user.
This patch is not intended to change the *users* of errors - only to
thread DiagnosticManagers to all the places where streams are used. I
also attempt to standardize our use of errors a bit, removing trailing
newlines and making clients omit 'error:', 'warning:' etc. and instead
pass the Severity flag.
The patch is testsuite-neutral, with modifications to one part of the
MI tests because it relied on "error: error:" being erroneously
printed. This patch fixes the MI variable handling and the testcase.

The swig typemaps had some magic for output File *'s on OS X that made:
SBDebugger.GetOutputFileHandle()
actually work. That was protected by a "#ifdef __MACOSX__", but the corresponding define
got lost going from the Darwin shell scripts to the python scripts for running
swig, so the code was elided. I need to pass the define to SWIG, but only when
targetting Darwin.
So I added a target-platform argument to prepare_bindings, and if that
is Darwin, I pass -D__APPLE__ to swig, and that activates this code again, and
GetOutputFileHandle works again. Note, I only pass that argument for the Xcode
build. I'm sure it is possible to do that for cmake, but my cmake-foo is weak.
I should have been able to write a test for this by creating a debugger, setting the
output file handle to something file, writing to it, getting the output file handle
and reading it. But SetOutputFileHandle doesn't seem to work from Python, so I'd
have to write a pexpect test to test this, which I'd rather not do.

That way you can set offset breakpoints that will move as the function they are
contained in moves (which address breakpoints can't do...)
I don't align the new address to instruction boundaries yet, so you have to get
this right yourself for now.

the xcode project file to catch switch statements that have a
case that falls through unintentionally.
Define LLVM_FALLTHROUGH to indicate instances where a case has code
and intends to fall through. This should be in llvm/Support/Compiler.h;
Peter Collingbourne originally checked in there (r237766), then
reverted (r237941) because he didn't have time to mark up all the
'case' statements that were intended to fall through. I put together
a patch to get this back in llvm http://reviews.llvm.org/D17063 but
it hasn't been approved in the past week. I added a new
lldb-private-defines.h to hold the definition for now.
Every place in lldb where there is a comment that the fall-through
is intentional, I added LLVM_FALLTHROUGH to silence the warning.
I haven't tried to identify whether the fallthrough is a bug or
not in the other places.
I haven't tried to add this to the cmake option build flags.
This warning will only work for clang.
This build cleanly (with some new warnings) on macosx with clang
under xcodebuild, but if this causes problems for people on other
configurations, I'll back it out.

On libc++ std::atomic is a fairly simple data type (layout wise, at least), wrapping actual contents in a member variable named "__a_"
All the formatters are doing is "peel away" this intermediate layer and exposing user data as direct children or values of the std::atomic root variable

This change restores the Xcode build to working after Makefile support
was stripped from LLVM and clang recently.
With this change, the Xcode build now requires cmake (2.8.12.2+).
The cmake must either be on the path that Xcode sees, or it must
exist in one of the following locations:
* /usr/local/bin/cmake
* /opt/local/bin/cmake
* $HOME/bin/cmake
If the ninja build tool is present on the path, it will be used.
If not, ninja will be cloned (via git), bootstrap-built, and
used for the llvm/clang build.
LLDB now requires a minimum deployment target of OS X 10.9. Prior
to this, it was 10.8. The llvm/clang cmake build will not run
with Xcode 7.2 or Xcode 7.3 beta's compiler with the minimum
deployment target set to anything lower than 10.9. This is
related to #include <atomic>.
When llvm or clang source code does not exist in the lldb tree,
it will be cloned via git using http://llvm.org/git/{project}.git.
Previously it used SVN. If this causes any heartache, we can
make this smarter, autodetect an embedded svn and use svn instead.
(And/or use SVN if a git command is not available).
This change also fixes an lldb-mi linkage failure (needed
libncurses) as exposed by one of the LLVM libs.

The python test run target started failing recently.
I tracked it down to what looks like the passing of
environment variables into the python script.
This locally fixes the vast majority of errors that
were ultimately inferior test build command failures.
Not sure what caused that to start happening.

A few files were accidentally added to the Copy Files build phase for our man
page, and they would appear when 'xcodebuild install' was invoked. This removes
those files – they continue to be built correctly, but they aren't installed
with our man page.

The Green Dragon LLVM builders are starting to parse xunit output
on LLDB Xcode builders. By default the XML formatter treats
xpass (unexpected successes) as failures. The new flag added
ensures we simply ignore those for purposes of xUnit output.
LLDB is not currently XPASS clean.

Most of the time CONFIGURATION_BUILD_DIR and BUILT_PRODUCTS_DIR are the same,
but they are different in 'xcodebuild install' situations. The file needs to be
put into BUILT_PRODUCTS_DIR or lldb's Python interface doesn't work when lldb is
built using 'xcodebuild install'.

Added a new flag, --allow-static-binding. When specified,
if (and only if) the swig binary cannot be found, then the
LLDBWrapPython.cpp and lldb.py from the
scripts/Python/{static-binding-dir} are copied into the place where
swig would have generated them.
{static-binding-dir} defaults to static-binding, and can be
overridden with the --static-binding-dir command line argument.
The static bindings checked in are from r253424.

This is no longer needed with --find-swig, and although innocuous on systems with
swig in the path, it blows up when there is no swig in the path. This should

The green dragon OS X builder doesn't have swig on the path.

This is only used by Xcode at the moment. It replaces the
buildSwigWrapperClasses.py and related per-script-language
scripts. It also fixes a couple bugs in those w/r/t Xcode
usage:
* the presence of the GCC_PREPROCESSOR_DEFINITIONS env var
should not be short-circuiting generation of the language
binding; rather, only if LLDB_DISABLE_PYTHON is present
within that environment variable.
* some logic around what to do when building in "non-Makefile"
mode. I've switched the handling of that to be on a
"--framework" flag - if specified, we build an OS X-style
framework; otherwise, we go with non.
Putting this up now only attached to the Xcode build so
others can look at it but not be affected by it yet.
After this, I'll tackle the finalizer, along with trying
it locally on Linux.
