Move some global statements to top of function

These were flagged by mediawiki/tools/code-utils/check-vars.php
because they were located inside a switch statement, or inside an
if statement and used outside the statement. All other warnings
from that script are bogus, mostly because the script has no
support for PHP 5.3 namespaces.
