Remove references to response file argument in CommandLine.rst

Browse Source 
Summary:
The documentation refers to a boolean that controls whether response files are
handled, but this is incorrect. Since r165535, response files are always
enabled.

customary to use the so-called 'response files' to circumvent this
restriction. These files are mentioned on the command-line (using the "@file")
syntax. The program reads these files and inserts the contents into argv,
thereby working around the command-line length limits. Response files are
enabled by an optional fourth argument to `cl::ParseEnvironmentOptions`_ and
`cl::ParseCommandLineOptions`_.
