PATCH: Improve version tagging

[Mark Mitchell <mark at codesourcery dot com>]

This patch makes the gccadmin cronjob that updates version.c files
more automated; it can now find all the branches to update by itself.

Tested by running the script to update version numbers.

Checked out in ~gccadmin.
