isRecoverableError is completely reimplemented using acorn and an
acorn plugin that examines the state of the parser at the time of the
error to determine if the code could be completed on a subsequent line.

This patch adds a `make format-cpp` shortcut to the Makefile
that runs clang-format on the C++ diffs, and a
`make format-cpp-build` to install clang-format from
npm.

To format staged changes:

```
$ make format-cpp
```

To format HEAD~1...HEAD (latest commit):

```
$ CLANG_FORMAT_START=`git rev-parse HEAD~1` make format-cpp
```

To format diff between master and current branch head (master...HEAD):

```
$ CLANG_FORMAT_START=master make format-cpp
```

Most of the .clang-format file comes from running

```
$ clang-format --dump-config --style=Google
```

with clang-format built with llvm/trunk 328768 (npm version 1.2.3)

The clang-format version is fixed because different version of
clang-format may format the files differently.
