58c44312af reserve sysFatal for Defect (#22158) 
Per manual, `panics:on` affects _only_ `Defect`:s - thus `sysFatal`
should not redirect any other exceptions.

Also, when `sysFatal` is used in `nimPanics` mode, it should use regular
exception handling pipeline to ensure exception hooks are called
consistently for all raised defects.

2b1a671f1c explicitly import using std/ in tempfiles.nim (#22851) 
At least on modern Nim `tempfiles` is not usable if the user has
https://github.com/oprypin/nim-random installed, because the compiler
picks the nimble path over the stdlib path (apparently).

816589b667 NIR: Nim intermediate representation (#22777) 
Theoretical Benefits / Plans: 

- Typed assembler-like language.
- Allows for a CPS transformation.
- Can replace the existing C backend by a new C backend.
- Can replace the VM.
- Can do more effective "not nil" checking and static array bounds
checking.
- Can be used instead of the DFA.
- Easily translatable to LLVM.
- Reasonably easy to produce native code from.
- Tiny memory consumption. No pointers, no cry.

**In very early stages of development.**

Todo:
- [x] Map Nim types to IR types.
- [ ] Map Nim AST to IR instructions:
  - [x] Map bitsets to bitops.
  - [ ] Implement string cases.
  - [ ] Implement range and index checks.
  - [x] Implement `default(T)` builtin.
  - [x] Implement multi string concat.
- [ ] Write some analysis passes.
- [ ] Write a backend.
- [x] Integrate into the compilation pipeline.

b60f15e0dc copyFile with POSIX_FADV_SEQUENTIAL (#22776) 
- Continuation of https://github.com/nim-lang/Nim/pull/22769
- See
https://pubs.opengroup.org/onlinepubs/9699919799/functions/posix_fadvise.html
- The code was already there in `std/posix` since years ago. 3 line
diff.

a38e3dcb1f copyFile with bufferSize instead of hardcoded value (#22769) 
- `copyFile` allows to specify `bufferSize` instead of hardcoded wrong
value. Tiny diff.


# Performance

- 1200% Performance improvement.


# Check it yourself

Execute:

```bash
for i in $(seq 0 10); do
  bs=$((1024*2**$i))
  printf "%7s Kb\t" $bs
  timeout --foreground -sINT 2 dd bs=$bs if=/dev/zero of=/dev/null 2>&1 | sed -n 's/.* \([0-9.,]* [GM]B\/s\)/\1/p'
done
```

(This script can be ported to PowerShell for Windows I guess, it works
in Windows MinGW Bash anyways).


# Stats

- Hardcoded `8192` or `8000` Kb bufferSize gives `5` GB/s.
- Setting `262144` Kb bufferSize gives `65` GB/s (script suggestion).

8bba04078c avoid AnyEnumConv warning in genEnumCaseStmt (#22061) 
When parsing enums from strings using `genEnumCaseStmt`, `AnyEnumConv`
warnings are generated due to conversion from integer value. It seems
possible meanwhile to refer to the actual `enum` value by symbol instead
of being required to do the conversion from `ord`, even when the `enum`
is defined in a `block`.
