ErrorOr<void> represents an operation that returns nothing, but can still fail.
It should be used in cases where you need the aditional user data that ErrorOr
provides over error_code.

[ObjCARC] Refactored out the inner most 2-loops from PerformCodePlacement into the method ConnectTDBUTraversals.

The method PerformCodePlacement was doing too much (i.e. 3x loops, lots of
different checking). This refactoring separates the analysis section of the
method into a separate function while leaving the actual code placement and
analysis preparation in PerformCodePlacement.

*NOTE* Really this part of ObjCARC should be refactored out of the main pass
class into its own seperate class/struct. But, it is not time to make that
change yet though (don't want to make such an invasive change without fixing all
of the bugs first).

- Add list of physical registers clobbered in pseudo atomic insts
  Physical registers are clobbered when pseudo atomic instructions are
  expanded. Add them in clobber list to prevent DAG scheduler to
  mis-schedule them after these insns are declared side-effect free.
- Add test case from Michael Kuperstein <michael.m.kuperstein@intel.com>

the body does not use them and it appears the body has positional parameters.

This can cause unexpected results as in the added test case.  As the darwin
version of gas(1) which only supported positional parameters, happened to
ignore the named parameters.  Now that we want to support both styles of
macros we issue a warning in this specific case.

This allows users to promote -Wincompatible-pointer-type warnings to
errors but keep those for "discard qualifiers" as warnings (if they
so desire).

This transform converts the usage of null pointer constants (e.g. NULL, 0,
etc.) in legacy C++ code and converts them to use the new C++11 nullptr
keyword.
- Added use-nullptr transform.
- Added C++11 support to the final syntax check. Used ArgumentAdjuster class to
  add -std=c++11 option to the command line options.
- Added tests for use-nullptr transform.
- Added tests that exercises both loop-convert and use-nullptr in the source
  file.

TODO: There's a known bug when using both -loop-convert and -use-nullptr at the
      same time.

template typename deductions on swap<> (used in string.cpp).  Use
decltype(errno) to replicate the type and qualifier information for holding the
errno value.  Because errno is expected to be assignable, there is no need to
use typename std::remove_const<decltype(errno)>::type to hold the value.

Add a few comments to the ObjC test cases.

Changing nextToken() in the UnwrappedLineParser to get the next
non-comment token. This allows us to correctly layout a whole class of
snippets, like:

if /* */(/* */ a /* */) /* */
  f() /* */; /* */
else /* */
  g();

Fixes a bug in the formatter where we would assume there is a previous
non-comment token.
Also adds the indent level of an unwrapped line to the debug output in
the parser.
