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

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

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.
