LLVM 13 not support

[evan0greenup]

Reporting a bug

• [* ] I have tried using the latest released version of llvmlite (most recent is
  visible in the change log (https://github.com/numba/llvmlite/blob/master/CHANGE_LOG).
• [* ] I have included a self contained code sample to reproduce the problem.
  i.e. it's possible to run as 'python bug.py'.

I have LLVM 13, but when I try to build llvmlite, It said that RuntimeError: Building llvmlite requires LLVM 10.0.x or 9.0.x, got '13.0.0'

Currently, LLVM 10 and 9 is too old. It would be nice to update llvm dependency to latest.

@evan0greenup thank you for the suggestion. We have been discussing supporting multiple LLVM versions and I hope to do this work during this quarter. The discussion is over here: #802 -- closing this as a duplicate for now.
