Unpatched llvm & clang

[SylvainCorlay]

Is there a means to build xeus-clang-repl without a patched llvm?

Maintaining patches flavors of clang and llvm on conda-forge has been a major hurdle for packaging Cling on conda-forge, and dropping this requirement would be a major upside of switching to xeus-clang-repl for us.

These patches are backports from existing llvm patches which (were) are not yet released. We also put some of the work-in-progress patches to get user experience with how they work. They generally add new features which will land in LLVM but are still under review.

So, yes, the ultimate goal is to ship xeus-clang-repl with regular llvm releases.
