David Benjamin 9b5028523f Check in a pristine copy of googletest.
Snapshotted from 5e7fd50e17b6edf1cadff973d0ec68966cf3265e in the
upstream repository:
https://github.com/google/googletest

Since standalone builds and bots will need this, checking in a copy
rather than require everyone use gclient, repo, git submodules or scary
CMake scripts is probably simplest.

Consumers with their own copies of googletest will likely wish to ignore
or even exclude this directory.
