There's a few php "dynamic" constants which refer directly to the
point in execution:
__FUNCTION__, __CLASS__, __FILE__, __LINE__

I don't believe it's possible to get all the functions that have been
executed in PHP, however, you can easily output the name of each
hook(action, filter) as it's fired in WordPress with this code
snippet:

add_action( 'all', function() { var_dump( current_filter() ); });

That'll execute on every WordPress hook, allowing you to see where
each hook is fired.. Can be very useful to work it out.
