Running clang-format over all of GoogleTest

A few tests are examining code locations and looking af the resulting line
numbers to verify that GoogleTest shows those to users correctly. Some of those
locations change when clang-format is run. For those locations, I've wrapped
portions in:
// clang-format off
...
// clang-format on

There may be other locations that are currently not tickled by running
clang-format.
