-Werror and -extra_checks flags don't work as documented

[ekuefler]

These flags are described at http://bazel.io/docs/bazel-user-manual.html#-Werror, but all of my attempts to pass them on the command line lead to errors:

Sorry for that these are flags for error-prone support that is not yet open-sourced.

I will remove that from the documentation.
