Don't include functions.php in wp_load_translations_early()

to avoid a parse error in a PHP4 environment (caused by use of
the clone keyword in option.php).

Manually include functions.php in the rare situations where it
is not already included by the time we need to load translations
early.

Remove the functions.php dependency by switching the wp_die() calls
to die(), in wp_check_php_mysql_versions().

props SergeyBiryukov, see #21316, for trunk.
