llvm/gnu-install-dirs.patch: I've dropped most of the changes to
docs/CMake.rst as they aren't relevant for Nixpkgs and the restructuring
of that file makes it a bit annoying to resolve them via Git.
This also fixes the libunwind build (even with GCC 11 it fails with):
/build/source/libunwind/src/libunwind.cpp:19:5: warning: "__has_feature" is not defined, evaluates to 0 [-Wundef]
19 | #if __has_feature(address_sanitizer)
| ^~~~~~~~~~~~~
/build/source/libunwind/src/libunwind.cpp:19:18: error: missing binary operator before token "("
19 | #if __has_feature(address_sanitizer)
| ^
And the openmp build which failed with this error:
/nix/store/a4yw1svqqk4d8lhwinn9xp847zz9gfma-bash-4.4-p23/bin/bash: CLANG_TOOL-NOTFOUND: command not found

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
