Refactoring: Extract GetCanonicalChildren.

This CL deduplicates children-traversal code that is needed by both
`Importer::GetItemIdsInSourceOrder` and by
`Importer::ImportDeclsFromDeclContext`.  This CL extracts this code into
a new `GetCanonicalChildren` helper function.

This CL should only have minimal, inconsequential impact on code
behavior:
1. The same children decls should be traversed before and after this CL.
2. The traversal order may be different (for children of
   `LinkageSpecDecl`).  This order should be mostly inconsequential
   because:
     * `ImportDeclsFromDeclContext` mostly cares about populating
        (unordered) `import_cache_`
     * `GetItemIdsInSourceOrder` explicitly/separately sorts
        the item ids it returns.

Crubit: C++/Rust Bidirectional Interop Tool

Build status

Extremely experimental interop tooling for C++ and Rust.

Please don‘t use, this is an experiment and we don’t yet know where will it take us. There will be breaking changes without warning. Unfortunately, we can't take contributions at this point.

Building Crubit

$ apt install clang lld bazel
$ git clone git@github.com:google/crubit.git
$ cd crubit
$ bazel build --linkopt=-fuse-ld=/usr/bin/ld.lld //rs_bindings_from_cc:rs_bindings_from_cc_impl

Using a prebuilt LLVM tree

$ git clone https://github.com/llvm/llvm-project
$ cd llvm-project
$ CC=clang CXX=clang++ cmake -S llvm -B build -DLLVM_ENABLE_PROJECTS='clang' -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=install
$ cmake --build build -j
$ # wait...
$ cmake --install build
$ cd ../crubit
$ LLVM_INSTALL_PATH=../llvm-project/install bazel build //rs_bindings_from_cc:rs_bindings_from_cc_impl
