Merge remote-tracking branch 'origin/master' into llvm11

Conflicts:
  cmake/Findllvm.cmake

The llvm11 branch changed 10's to 11's and master branch added the
"using LLVM_CONFIG_EXE" help message, so the resolution was to merge
these changes together.

I also added a check to make sure LLVM is built with AVR enabled, which
is no longer an experimental target.
