what's the plan with llvm-toolchain-*

Hello,

First, thanks for asking and I apologize for not communicating more on this.

My target is to have 2 versions for the next release. Realistically,
because of all the use
cases (ex: ghc), it is hard to have all packages focusing only one
version of llvm.

Currently, I am clearly failing at this. ;)
LLVM upstream is going through some significant changes in term of build
systems. I have been focusing
on bringing 12 & 13 at this level (they both have failures currently).

Once they are green, I will work on the transition to 12 or (probably?)
13 and the removal of the older.

Hope this is clear,
Cheers
