fixes#24801
Because distinct `seq` types match `proc `=destroy`*[T](x: var T)
{.inline, magic: "Destroy".}`. But the Nim compiler generates lifted seq
types for corresponding distinct types. So we skip the address for
distinct types.
Related to https://github.com/nim-lang/Nim/pull/22207 I had a hard time
finding the other place where generic destructors get replaced by
attachedDestructors

fixes#24319
`byRefLoc` (`mapType`) requires the Loc `a` to have the right type.
Without `lfEnforceDeref`, it produces the wrong type for `deref (var
array)`, which may come from `mitems`.
(cherry picked from commit 0347536ff2)
It speeds up
```nim
proc foo =
let piece = cast[seq[char]](newSeqUninit[uint8](5220600386'i64))
foo()
```
Notes that `cast[ref](...)` is excluded because we need to keep the ref
alive if the parameter is something with pointer types (e.g.
`cast[ref](pointer)`or `cast[ref](makePointer(...))`)

For backwards compatibilities, we might need to keep the changes under a
preview compiler flag. Let's see how many packags it break.
**TODO** in the following PRs
- [ ] Turn the `var T` destructors warning into an error with
`nimPreviewNonVarDestructor`

ref #23354
The new move analyzer requires types that have the tfAsgn flag
(otherwise `lastRead` will return true); tfAsgn is included when the
destructor is not trival. But it should consider the assignement for
objects in this case because objects might have a trival destructors but
it's the assignement that matters when it is passed to sink parameters.

* Add use of Windows Wide CRT API for env. vars
Replaces use of CRT API `getenv` and `putenv` with respectively
`_wgetenv` and `_wputenv`. Motivation is to reliably convert environment
variables to UTF-8, and the wide API is best there, because it's
reliably UTF-16.
Changed the hack in `lib/std/private/win_setenv.nim` by switching the
order of the Unicode and MBCS environment update; Unicode first, MBCS
second. Because `_wgetenv`/`_wputenv` is now used, the Unicode
environment will be initialized, so it should always be updated.
Stop updating MBCS environment with the name of `getEnv`. It's not
necessarily true that MBCS encoding and the `string` encoding is the
same. Instead convert UTF-16 to current Windows code page with
`wcstombs`, and use that string to update MBCS.
Fixes regression in `6b3c77e` that caused `std/envvars.getEnv` or
`std/os.getEnv` on Windows to return non-UTF-8 encoded strings.
Add tests that test environment variables with Unicode characters in
their name or value.
* Fix test issues
Fixes
* `nim cpp` didn't compile the tests
* Nimscript import of `tosenv.nim` from `test_nimscript.nims` failed
with "cannot importc"
* Fix missing error check on `wcstombs`
* Fix ANSI testing errors
* Separate ANSI-related testing to their own tests, and only executing
them if running process has a specific code page
* Setting locale with `setlocale` was not reliable and didn't work on
certain machines
* Add handling of a "no character representation" error in second
`wcstombs` call
* tests/newruntime_misc: Increment allocCount
Increments overall allocations in `tnewruntime_misc` test. This is
because `getEnv` now does an additional allocation: allocation of the
UTF-16 string used as parameter to `c_wgetenv`.
* Revert "tests/newruntime_misc: Increment allocCount"
This reverts commit 4d4fe8bd3e.

* Fix global destructor injection for JS backend
* Moved global destructors injection before the final call to transform and
generate JS code. It had previously been after and thus not no JS was
generated for them.
* Added some internal documentation of `jsgen`.
* Enable a current destructor test to cover the JS backend as well.
* Fixes the JS aspect of #17237.
* Fixed global destructor injection order for JS backend

This alters the DFA control flow graph generation for case statments.
Gotos are now generated as a chained link, this ensures that evaluation
of variant branches collapses as early as possible, without hitting the
2k call limit.
