bash completion: Add --autostash and --no-autostash to pull

Ideally we should only autocomplete if pull has --rebase since they only work with it but could not figure out how to do that and the error message of doing git pull --autostash points out that you need --rebase so i guess it's good enough

You could use the completion script's __git_find_on_cmdline() helper function to easily check whether the '--rebase' option is already present on the command line.

Having said that, I don't think we should go there, it feels that's trying to be overly and unnecessarily clever. After all, the order of command line options doesn't matter, and 'git pull --autostash --rebase' is a perfectly legit command.
