substituteStream(): WARNING: pattern '# define _LIBCPP_USE_AVAILABILITY_APPLE' doesn't match anything in file 'include/__config'
The new mechanism for those is a cmake option
LIBCXX_ENABLE_VENDOR_AVAILABILITY_ANNOTATIONS that is off by default:

The version will initially remain the same so that no additional changes
to the packaging are required (i.e. this commit only includes the
required changes to build from the mono repository instead of individual
tarballs).
The purpose of this package is to continuously improve the LLVM
packaging in Nixpkgs without causing a lot of rebuilds and provide more
recent LLVM builds for users. For more details see:
https://github.com/NixOS/nixpkgs/issues/114828
The main thing was using `llvm_meta` in all versions.
Secondarily:
- libunwindx7: Forgot to split outputs
- libcxx{,abi} 12: Forgot to apply output-splitting patches.
- simplify `useLLVM` stdenv-switching logic.
- openmp always gets its own directory
This might be a bit debatable but upstream uses "xx" instead of "++"
when using it as identifier / in the code (file/directory names, build
scripts, website URLs, etc.) so we should probably too.
And at least the attribute name and pname will be consistent now.
We can use use `stdenv.hostPlatform.isStatic` instead, and move the
logic per package. The least opionated benefit of this is that it makes
it much easier to replace packages with modified ones, as there is no
longer any issue of overlay order.

Additionally cherry-picked 3 commits from `llvm-project/master`:
- llvm/llvm-project@d21664c
- llvm/llvm-project@3a0f6e6
- llvm/llvm-project@87dac7d
such that clang can automatically pick up the polly plugin from the
`llvm-polly` build.
* starting with rc2
* make `lldb` compilable again on Darwin
* separate out manpage creation for `lldb` into a new derivation
* minor tweaks to the patching of sources,
some of which are backportable to earlier versions
Adds pkgsCross.wasm32 and pkgsCross.wasm64. Use it to build Nixpkgs
with a WebAssembly toolchain.
stdenv/cross: use static overlay on isWasm
isWasm doesn’t make sense dynamically linked.
this adds libc++ to the LLVM cross, giving us access to the full
Nixpkgs set. This requires 4 stages of wrapped compilers:
- Clang with no libraries
- Clang with just compiler-rt
- Clang with Libc, and compiler-rt
- Clang with Libc++, Libc, and compiler-rt
