This commit does the following.
- Converts the test to a gtest, including renaming the directory.
- Factors out the duplicated checking code into a separate Check() function.
- Avoids printing any output unless a failure occurs. (The gtest harness prints
out minimal output, like the name of the current test.)
- Removes SampleWordBreakUsage(), which prints some output but doesn't actually
test anything, and so isn't useful.
