Introduce _LIBCPP_STD_VER.  This can be set by the client (or the clang driver).  Or it will be defaulted.  The default is 11 if -std= c++11 or eariler, else it will default to the current year modulo the century.  We anticipate it defaulting to 14 for C++14 when the time comes.  For now, post-C++11 libcxx implementations should protect themselves with #if _LIBCPP_STD_VER > 11.

This module uses Python's sys.settrace() mechanism so setup a hook that can log every significant operation
This is a first step in providing a good debugging experience of Python embedded in LLDB
This module comprises an OO infrastructure that wraps Python's tracing and inspecting mechanisms, plus a very simple logging tracer
Output from this tracer looks like:

call print_keyword_args from <module> @ 243 args are kwargs are {'first_name': 'John', 'last_name': 'Doe'}
running print_keyword_args @ 228 locals are {'kwargs': {'first_name': 'John', 'last_name': 'Doe'}}
running print_keyword_args @ 229 locals are {'key': 'first_name', 'value': 'John', 'kwargs': {'first_name': 'John', 'last_name': 'Doe'}}
first_name = John
running print_keyword_args @ 228 locals are {'key': 'first_name', 'value': 'John', 'kwargs': {'first_name': 'John', 'last_name': 'Doe'}}
running print_keyword_args @ 229 locals are {'key': 'last_name', 'value': 'Doe', 'kwargs': {'first_name': 'John', 'last_name': 'Doe'}}
last_name = Doe
running print_keyword_args @ 228 locals are {'key': 'last_name', 'value': 'Doe', 'kwargs': {'first_name': 'John', 'last_name': 'Doe'}}
return from print_keyword_args value is None locals are {'key': 'last_name', 'value': 'Doe', 'kwargs': {'first_name': 'John', 'last_name': 'Doe'}}

C++1y: Update __cplusplus to temporary value 201305L to allow detection of provisional C++1y support.
Add __has_feature and __has_extension checks for C++1y features (based on the provisional names from
the C++ features study group), and update documentation to match.

Apparently we didn't keep an association of Compile Unit metadata nodes
to DIEs so looking up that parental context failed & thus caused no
DW_TAG_imported_modules to be emitted at the CU scope. Fix this by
adding the mapping & sure up the test case to verify this.

Summary:
Added parseConfiguration method, which reads FormatStyle from YAML
string. This supports all FormatStyle fields and an additional BasedOnStyle
field, which can be used to specify base style.

Move this function to sanitizer_common because LSan uses it too. Also, fix a bug
where the TLS range reported for main thread was off by the size of the thread
descriptor from libc (TSan doesn't care much, but for LSan it's critical).

createSystemZMCCodeGenInfo was not passing the optimization level to

With this change, __internal_*stat always expect a "struct stat *" argument.
This avoids stat/stat64 caller-side confusion (sanitizer_common tests already
made this mistake), and allows the use of __internal_fstat() as a drop-in
replacement for libc's fstat().

This is just a slight improvement for the fix in r181299, which fixes
formatting the very last line of a file.

Emacs seems to have a line that is just past the last character of the
buffers content. This needs to be handled specially so that clang-format
is not called with an invalid -offset.

Use the new cl::OptionCategory support to move the Polly options into a separate
option category. The aim is to hide most options and show by default only the
options a user needs to influence '-O3 -polly'. The available options probably
need some care, but here is the current status:

Polly Options:
Configure the polly loop optimizer

  -enable-polly-openmp              - Generate OpenMP parallel code
  -polly                            - Enable the polly optimizer (only at -O3)
  -polly-no-tiling                  - Disable tiling in the scheduler
  -polly-only-func=<function-name>  - Only run on a single function
  -polly-report                     - Print information about the activities
                                      of Polly
  -polly-vectorizer                 - Select the vectorization strategy
    =none                           -   No Vectorization
    =polly                          -   Polly internal vectorizer
    =unroll-only                    -   Only grouped unroll the vectorize
                                        candidate loops
    =bb                             -   The Basic Block vectorizer driven by
