Markus Triska 98086de77e attach more propagators before starting propagation 
This prevents repeated triggering of already attached propagators
while new propagators are being attached to involved variables.

Markus Triska 24456e9703 remove optional (+)/1 prefix in get_atts/2 and put_atts/2 calls 
The (+)/1 prefix in get_atts/2 at line 4219 by itself already causes a
greater than 15% slowdown for the benchmark shown in #1730:

    ?- N #= 2^14,
       time(((between(1, N, _),
              X #\= Y,
              false)
            ; true)).

The performance impact is not a good reason to remove the optional
(+)/1 prefix! Performance issues should be addressed at the root, in
this case get_atts/2 (#1962). We should never manually work around
performance issues in built-in predicates.

In contrast, readability is a good argument, and I find the calls
slightly easier to read without the optional (+)/1 prefix.

The prefix is now consistently omitted when possible.

for crrl which makes this possible!
