LLVM 14 update

[jusito]

Because you created already a pull request and latest ci failed after components.json.

Fixed it and merged most changes from llvm-core recipe + updated it here and there.
There are still some smaller todos, but recipe is working again, so what do you think?

Edit:

• shared / static are sometimes mixed, for some enabled projects shared / static lib creation seems crossed, e.g. omp.so in static and omp.a in shared build. According to documentation using BUILD_SHARED_LIBS shouldn't be used.
• for shared build all non shared libs are removed, should we add it for static as well?

@sykhro Iam currently optimizing the conan2 migration, minimal configuration and most others are looking fine at the end of the day. Do you have time testing it on windows?

Yeah, happy to test whenever you’re ready.
Unfortunately on Windows the DIASDK is needed for PDB generation. We have made a recipe for it so that LLVM doesn’t go fetching it from the visual studio installation, but it’s a bit problematic to fix properly

@sykhro merged my latest changes, so I tested llvm 13,14,15,16 in latest patch version in minimal, complete, with dynlib.

edit:
llvm 13,14,15,16 on linux with clang 15

• every with_{project,runtime}=False = minimal configuration
• every with_{project,runtime}=True = complete configuration
  • compiler-rt/libc/lldb seems like they always need some special handling. compiler-rt needs system libs, libc produces a compiler crash, lldb
• llvm_build_llvm_dylib=True tested and test_package checks for it too
  Iam currently looking into libxml2 issues with lldb, tests seem to run whole night but looks good as of now.

So in essence, minimal / minimal+clang / minimal+clang+dynlib would be a good start if that is working fine.
Does it match your preferred configuration?

If you see anything which looks strange or isn't well documented but should be in your opinion, always welcome as feedback.

cheers
