After final improvements to the official formatter implementation,
this commit now performs the first treewide reformat of Nix files using it.
This is part of the implementation of RFC 166.
Only "inactive" files are reformatted, meaning only files that
aren't being touched by any PR with activity in the past 2 months.
This is to avoid conflicts for PRs that might soon be merged.
Later we can do a full treewide reformat to get the rest,
which should not cause as many conflicts.
A CI check has already been running for some time to ensure that new and
already-formatted files are formatted, so the files being reformatted here
should also stay formatted.

Fail to build with ninja 1.12 when NIX_BUILD_CORES is low (Hydra or Github Actions):
```
ld: warning: directory not found for option '-L/nix/store/g9rbp9m6vs1xj4jl6b6vjb6bm8kgr107-SDKs/MacOSX10.15.sdk/usr/lib/swift'
...
ld: warning: Could not find or use auto-linked library 'swiftCompatibility56'
Undefined symbols for architecture arm64:
"__swift_FORCE_LOAD_$_swiftCompatibility56", referenced from:
__swift_FORCE_LOAD_$_swiftCompatibility56_$_Optimizer in libswiftCompilerModules-bootstrapping1.a(Optimizer.o)
...
```
Can reproduce using `nix --option cores 2 build -f . swiftPackages.swift-unwrapped`.
Until we find out the exact cause, follow [swift upstream][1], pin ninja to version
1.11.1.

Swift releases are associated with particular Darwin SDK versions. They
don’t _have_ to use that version, but it makes sense to use that version
by default. The deployment target is set to the supported Swift minimum
versions. Unlike C and C++, Swift requires you to availability
annotations, so propagating a newer SDK should be safe.
libarclite is needed to support ARC on very old deployment targets
(10.10 and older). None of these deployment targets are supported
deployment targets in nixpkgs, especially for Swift. This removes the
need to package the command-line tools executables.
Swift’s build makes a few assumptions about how the SDK is set up that
are not true anymore with the new SDK. Fix it to find the SDK at
`$SDKROOT` and copy additional stubs it needs to bootstrap.
In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages
https://www.github.com/NixOS/nixpkgs/pull/343059
There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.

Since theey is not active in a long span of time.
None of the packages in this commit are orphan.
All the packages listed here are related to Swift programming language compiler
suite.
We already did this for -march in 12b0e8ac74 ("clang: don't set
-march for overridden target"), but it should have been done for all
machine flags, for the same reason.
Example bug this fixes:
nix-shell -E '
with import ./. {
crossSystem = {
system = "powerpc64le-linux";
gcc.cpu = "power10";
};
};
clangStdenv.mkDerivation { name = "test"; }
' --run '$CC -target wasm32-unknown-unknown -c /dev/null'
Which previously failed with:
clang: error: unsupported option '-mcpu=' for target 'wasm32-unknown-unknown'
The nixpkgs-unstable channel's programs.sqlite was used to identify
packages producing exactly one binary, and these automatically added
to their package definitions wherever possible.
swiftc uses cc-wrapper which sets the -march flag on some systems which
breaks the build. This change adds a flag, disableMarch, to cc-wrapper
which disables using the -march flag.

- merge libcxxabi into libcxx for LLVM 12, 13, 14, 15, 16, 17, and git.
- remove the link time workaround `-lc++ -lc++abi` from 58 packages as it is no longer required.
- fixes https://github.com/NixOS/nixpkgs/issues/166205
- provides alternative fixes for. https://github.com/NixOS/nixpkgs/issues/269548https://github.com/NixOS/nix/issues/9640
- pkgsCross.x86_64-freebsd builds work again
This change can be represented in 3 stages
1. merge libcxxabi into libcxx -- files: pkgs/development/compilers/llvm/[12, git]/{libcxx, libcxxabi}
2. update stdenv to account for merge -- files: stdenv.{adapters, cc.wrapper, darwin}
3. remove all references to libcxxabi outside of llvm (about 58 packages modified)
### merging libcxxabi into libcxx
- take the union of the libcxxabi and libcxx cmake flags
- eliminate the libcxx-headers-only package - it was only needed to break libcxx <-> libcxxabi circular dependency
- libcxx.cxxabi is removed. external cxxabi (freebsd) will symlink headers / libs into libcxx.
- darwin will re-export the libcxxabi symbols into libcxx so linking `-lc++` is sufficient.
- linux/freebsd `libc++.so` is a linker script `LINK(libc++.so.1, -lc++abi)` making `-lc++` sufficient.
- libcxx/default.nix [12, 17] are identical except for patches and `LIBCXX_ADDITIONAL_LIBRARIES` (only used in 16+)
- git/libcxx/defaul.nix does not link with -nostdlib when useLLVM is true so flag is removed. this is not much different than before as libcxxabi used -nostdlib where libcxx did not, so libc was linked in anyway.
### stdenv changes
- darwin bootstrap, remove references to libcxxabi and cxxabi
- cc-wrapper: remove c++ link workaround when libcxx.cxxabi doesn't exist (still exists for LLVM pre 12)
- adapter: update overrideLibcxx to account for a pkgs.stdenv that only has libcxx
### 58 package updates
- remove `NIX_LDFLAGS = "-l${stdenv.cc.libcxx.cxxabi.libName}` as no longer needed
- swift, nodejs_v8 remove libcxxabi references in the clang override

Failing Hydra build: https://hydra.nixos.org/build/249763077/nixlog/12
The problem is that glibc commit
64b1a44183a3094672ed304532bedb9acc707554 marked the `FILE*` argument of a few
functions including `fread` & `ferror` as non-null. The applied patch
("Android: add better nullability checks for nullability annotations added in NDK 26")
is targeted for the Android platform, but fixes said issue as well: the
handle returned from `fopen` is of type `Optional<T>` and the `guard`
expression unwraps that now (and throws an exception if `nil` is
returned). The previous `nil`-check didn't modify the type of `fp`, but
only raised the exception and moved on with `Optional<T>`.
It's a little sad that the patch needs to be applied at so many places,
but I guess that's what you get with language-level package managers 🤷
Also, seems good-enough to me given that it's actually temporary, the
patch is already upstream and will probably be obsolete at one of the
next Swift updates.
