[cfe-dev] [Release-testers] LLVM 11.0.1-rc1 has been tagged

[Nico Weber via cfe-dev]

https://bugs.llvm.org/show_bug.cgi?id=46647 (check-llvm)
https://bugs.llvm.org/show_bug.cgi?id=46644 (check-clang
check-lld is fine, haven't tried anything else yet. What would the goal be?
Make sure the 11.0 branch isn't worse than trunk?
