709dc041eb FIXED: correct partial string tail calculation in arg/3 
This addresses another aspect of #2924, found by @haijinSk.
Thank you again!

Example:

    ?- "aaaaaaa" = [_,_,_,_,_,_|T], arg(2, T, 2).
       false.

8763a42c98 FIXED: arg/3 for partial strings 
This address #2924, reported by @haijinSk. Thank you a lot!

Example:

    ?- arg(2, "a", A).
       A = [].

The fact that such a mistake in macro usage is even possible could be
a sign that the macro definition should be stricter.

d51cbd67e0 ENHANCED: partial_string/3 no longer creates atoms 
As a consequence, resulting strings are now quickly reclaimed on
backtracking.

This addresses #2912.

Test case:

    :- use_module(library(iso_ext)).
    :- use_module(library(lists)).

    ab(a).
    ab(b).

Sample query:

    ?- length(Ls, 1_000_000),
       maplist(ab, Ls),
       partial_string(Ls, Es0, []),
       Es0 == Ls.
       Ls = "aaaaaaaaaaaaaaaaaaa ...", Es0 = "aaaaaaaaaaaaaaaaaaa ..."
    ;  Ls = "aaaaaaaaaaaaaaaaaaa ...", Es0 = "aaaaaaaaaaaaaaaaaaa ..."
    ;  Ls = "aaaaaaaaaaaaaaaaaaa ...", Es0 = "aaaaaaaaaaaaaaaaaaa ..."
    ;  Ls = "aaaaaaaaaaaaaaaaaaa ...", Es0 = "aaaaaaaaaaaaaaaaaaa ..."
    ;  Ls = "aaaaaaaaaaaaaaaaaaa ...", Es0 = "aaaaaaaaaaaaaaaaaaa ..."
    ;  ... .

running in constant memory.

e9bb41f0d6 ENHANCED: use a fast test for the expected case of chars in atom_chars/2 etc. 
Suggested by Oleg Finkelstein, thank you a lot!

Example, before this change:

    ?- t+\(length(As, 1_000_000), maplist(=(a), As), time(atom_chars(A, As))).
       % CPU time: 0.693s, 7_000_041 inferences
       true.

Now:

    ?- t+\(length(As, 1_000_000), maplist(=(a), As), time(atom_chars(A, As))).
       % CPU time: 0.080s, 40 inferences
       true.

This also partially ameliorates #2907.

bf31d3f9a9 ENHANCED: dedicated faster branches for repositionable streams 
rebis-dev makes the speed difference especially apparent due to the
linear scan of strings on the heap in partial_string_tail/2 which is
now avoided for repositionable streams, notably files.

This addresses #2888 reported and analyzed by @haijinSk. Many thanks!

15f1320d05 Fix allocate_pstr randomly refusing to properly allocate memory 
This one was a toughie: it turns out that using `ptr::align_of()`` was
a bad idea, since the buffer in `Heap` itself is not aligned to
`Heap::heap_cell_alignment()`, so `ptr::align_of()` would sometimes
return lower values than expected.

That made for an heisenbug: if the alignment of the heap happened to be 4,
then the bug wouldn't trigger.
