New function `has_archive_post_type()`

[sebastian.pisula]

Function will be check that custom post type has archive. For example:

<?php if(has_archive_post_type('cpt')) : ?>
<a href="<?php echo get_post_type_archive_link('cpt');?>">My Special Archive Link</a>
<?php endif;?>

get_post_type_archive_link returns false when a post type doesn't have an archive. You could just do:

<?php if( get_post_type_archive_link( 'cpt' ) ) : ?>
<a href="<?php echo get_post_type_archive_link( 'cpt' ); ?>">My Special Archive Link</a>
<?php endif; ?>

Closing as per my last comment.
