There is a process for this that's documented here:
https://llvm.org/docs/DeveloperPolicy.html#id23

An RFC like this should be written:
https://lists.llvm.org/pipermail/llvm-dev/2019-January/129452.html

I don't think anything is blocking it except that someone needs to do
the work to investigate the different toolchains and summarize it in a
RFC email to the list.
