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.

This is backwards compatible with earlier integrations.
Also adds a basic test and a test for the ranges integration.
You can now run:
clang-format -offset=42 -length=15 -offset=150 -length=22
To re-format the ranges (42, +15) and (150, +22).

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.

cpp11-migrate now contains the loop convert transform code and tests.
Cleaning up the old code/tests and updating build system files as
necessary.

- Turned off -count-only tests as they aren't supported in cpp11-migrate
yet.
- Updated tests to use new binary name and options to access
loop-convert transform.
- Fixed header guards to not use restricted names.

Took existing code from loop-convert tool and made it into a cpp11-migrate
transform. Pattern now set for having transform code in subdirectories. Related
changes:
- Makefile and CMakeLists.txt updated to support source files in
subdirectories.
- At least one transform must be specified. syntax-only tests removed to
reflect this.
- TODO: port over loop-convert tests.

- Added directory structures and build system files for the new tool.
- Extremely basic implementation of tool performs only an initial syntax check.
- Basic tests ensure syntax test works as expected.

Seems I had a problem with my version of grep, when run by lit, not supporting
the \s escape. This seems to fix it for me & I'll be getting the buildbots to
run these tests too to keep an eye on them (actually loop-convert tests still
fail when run via a make build, so that'll be addressed in a future commit). I
could use [[:space:]] to generalize over other whitespace but that seemed
unnecessarily verbose when the flexibility wasn't actually required by the
current text of the tests.
Also I just simplified a lot of the loop-convert tests (removing the
unecessary temp file deletion at the start, removing the unnecessary && for
FileCheck, etc).
The remove-cstr-calls/basic.cpp changes were necessitated by an out of tree
lit-like test runner that's a bit less fantastic about escaping. They were
modeled on existing tooling test cases in Clang, with thanks to Manuel Klimek
for the pointers.

A new Clang-based tool which converts for loops to use the range-based
syntax new to C++11. Three kinds of loops can be converted:
- Loops over statically allocated arrays
- Loops over containers, using iterators
- Loops over array-like containers, using operator[] and at()
Each transformation is assigned a confidence level by the tool. The
minimum require confidence level to actually apply the transformation
can be specified on the command line, but the default level should be
fine for most code.
Like other tools based on RefactoringTool, it is easiest to use this
tool with a compilation database.

Loop Converter Skeleton - array-step-1
Added a check to loop increments - array-step-2b
Added a check on the loop's condition expression - array-step-2c
Finished array matcher - array-step-2
Retrieved matched nodes - array-step-3
Analysis for array loop indices - array-step-4
Added checking for naming and variable scope
Added confidence level and count-only command line args
Added aliased variable elision
Added support for iterator-based loops
Added support for single-iterator loops which call end() repeatedly
Added support for converting array-like containers

With this we can build and test the remove-cstr-calls tool which should
serve as a good example of how to add tools and their tests to the
repository.
