[PATCH] D34924: [Bash-autocompletion] Check if bash-completion is installed

[Yuka Takahashi via Phabricator via cfe-commits]

yamaguchi created this revision.

Bash-autocompletion for clang depends on bash-completion system and abort `bash:
_init_completion: command not found` when it is not installed.

Changed to return silently if bash-completion is not installed.
