Edwin Vane b76a13eb4e cpp11-migrate: Transforms collect timing data.
Using updated form of newFrontendActionFactory(), Transforms now automatically
measure, if requested, how long it takes to apply a MatchFinder to a source
file. Other per-transform overhead, e.g. applying replacements, is not
currently measured. This behaviour is disabled for now and soon will be
connected to a new command line arg.

Ariel J. Bernal f78debd7d2 Refactor Usenullptr matcher to avoid duplication
Previously UseNullptr matched separately implicit and explicit casts to nullptr,
now it matches casts that either are implict casts to nullptr or have an
implicit cast to nullptr within.

Also fixes PR15572 since the same macro replacement logic is applied to implicit
and explicit casts.

Dmitri Gribenko f68a5280cb Added summary option to cpp11-migrate tool
Added a summary option that enables output to stdout counting the number of
changes each transform has accepted, rejected or deferred.

Patch by Ariel Bernal.

Edwin Vane dd4743d18a Propagate changes through no-op transforms
Currently, changes made by previous transforms are not kept if a transform
doesn't make any changes itself to a given file. Now file states are propagated
properly through transforms that don't make changes.

Edwin Vane 37fea69391 Fix for combined loop and nullptr convert tests
The rewriter was previously reading the content buffer from the file itself.
Since we are now keeping the content in memory and writing to the file only
once, the rewriter's buffer (from the file) was not in sync with the
RefactoringTool's buffer. Adding an overrideFileContents call (similar to how
Clang-format handles for this) will resolve this issue.

Edwin Vane 44c3145938 Add use-nullptr transform to cpp11-migrate
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.
