[patch] Add swap files for vim to .gitignore

[Thomas Koenig via Gcc-patches]

Add swap files for vim to .gitignore.

This patch adds the most common swap files for vim to .gitignore. The
editor may leave those behind if is stopped or crashes.  We already
do the same kind of things for emacs.

ChangeLog:

        * .gitignore: Add swap files for vim.
