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.

A segfault used to clear the entire buffer. With this change, a message
to report a bug is displayed instead.
This should solve most cases similar to llvm.org/PR14774.

We should also install the clang-format.py script somewhere that makes
since for a Vim integration script. I don't know where that is though,
so just installing the binary for now. This is enough to let me use the
script from a checkout combined with the installed (and thus less likely
to crash or be slow) clang-format binary.

- 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.

Reads a single source range (offset, length) as well as the style guide
as parameters and then reformats everything it receives from stdin.

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.

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.
