cast
UseNullptr previously matched the implicit cast to const pointer as well as
the explicit cast within that has an implicit cast to nullptr as a descendant.
-Refactored UseNullptr to avoid special-casing certain kinds of cast sequences
-Added test cases.

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.

The Use-Nullptr transform was replacing nullptr_t-typed expressions because in
the AST such expressions have an implicit NullToPointer cast around them. Now
the transform ignores these expressions.
Fixes PR15414.

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.
