c7ec5a13a5 remove locks from AtomTable 
there are technically still two locks
- the Mutex to serialize consurrent updates to the AtomTable
- the RwLock as part of GLOBAL_ATOM_TABLE

the former is the age lock of RESIZE ATOM TABLE in <https://arxiv.org/pdf/1608.00989.pdf>, though we use it for the whole update as we don't match the whole structure and can't reserve an atom slot as is, so we need to also lock concurrent updates without resizing

the later should be uncontendet as we only write AtomTable::new iff the current value is a dangling Weak

aca0de06cd FIXED: make occurs_check and answer_write_options flags discoverable 
Quoting from 7.11 Flags:

   NOTE - A built-in predicate current_prolog_flag(Flag, Value)
   (8.17.2) enables a program to discover all the flags supported
   by a processor and their current values.

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

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.
