Subject: clang-format 2014-12-03 (new formula)

clang-format is a versatile source code formatter, part of the clang
(and thus llvm) project. It can be used for C++, ObjC, Java, and
JavaScript.

The build is using cmake and ninja for speed; building all of llvm or
using configure and make is very slow.

clang-format is released in roughly monthly testing pushes, tracked by
the subversion tags in "google/testing/yyyy-MM-dd". This formula uses
tarballs from github that correspond to the resolved tags.

Closes #35777.
