fixes#23587
As explained in the issue, `getOrDefault` has a parameter named
`default` that can be a proc after generic instantiation. But the
parameter having a proc type [overrides all other
overloads](f73e03b132/compiler/semexprs.nim (L1203))
including the magic `system.default` overload and causes a compile error
if the proc doesn't match the normal use of `default`. To fix this, the
`result = default(B)` initializer call is removed because it's not
needed, `result` is always set in `getOrDefaultImpl` when a default
value is provided.
This is still a suspicious behavior of the compiler but `tables` working
has a higher priority.
Hello, I am the original developer credited in this file.
I no longer wish to be credited for the it so I've updated it to say
"Nim Contributors".
This is a quick edit from the GitHub Web UI so let me know if I need to
make any changes to get this merged.
Thank you.

fixes#16771
follow up https://github.com/nim-lang/Nim/pull/16536
Ideally it should be handled in the IR part in the future
I have also checked the double evaluation of `swap` in the JS runtime
https://github.com/nim-lang/Nim/issues/16779, that might be solved by a
copy flag or something. Well, it should be best solved in the IR so that
it doesn't bother backends anymore.
It seems Deque doesn't need `mask` field because `data.len - 1` equals
to `mask`.
Deque without `mask` field passes test `tests/stdlib/tdeques.nim`.

In these cases, the tables/sets are clears or elements are deleted from
them. It's reasonable to suppress warnings because the value is not
accessed anymore, which means it's safe to ignore the warnings.

…eDefault` warnings
avoid issues mentioned by https://forum.nim-lang.org namely, it
allocated unnecessary stack objects in the loop
```c
while (1)
{
tyObject_N__8DSNqSGSHBKOhI8CqSgAow T5_;
nimZeroMem((void *)(&T5_), sizeof(tyObject_N__8DSNqSGSHBKOhI8CqSgAow));
eqsink___test4954_u450((&(*t_p0).data.p->data[i].Field1), T5_);
}
```
It might be more efficient in some cases

* Add `minmax` to sequtils
This adds a `minmax` proc to complement `min` and `max`; it computes
both results in a single pass for efficiency.
* Update lib/pure/collections/sequtils.nim
* Add minmax note to changelog.

`len` could contain side effects and may result in different values when
substituted twice in the template expansion. Instead, capture the result
of substituting `len` once.

Not copying the full call tree before the typedesc call check

* Add sink and lent to critbits
* Remove lent for pairs
I guess lent doesn't work well inside tuples
* Remove lent from template in critbits
Apparently this also doesn't work, because some checks failed
