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
InitMCCodeGenInfo(), so -O0 would be ignored.  Fixes DebugInfo/namespace.ll

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.

llvm-svn: 181303

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
                                        Polly

Unnamed bitfields won't have an explicit copy operation
