> This patchset adds tests for LLDB and GDB debugger extensions via the
> first commit. The next two commits refactor the LLDB extension and sort
> initialized commands alphabetically. The fourth commit adds the
> lightuserdata support for LJ_64 for LLDB too. The next commit joins
> extension logic into the single file, making the LuaJIT-related code
> debugger-agnostic. The last commit adds the CI workflow for arm64 and
> x86_64 architectures.
