[10.0.0 Release] Release Candidate 5 is here

Hi Hans,

I wonder if you are planning for RC6. There’s a bug reported recently for CET exception landing pad https://bugs.llvm.org/show_bug.cgi?id=45182 and a corresponding fix https://github.com/llvm/llvm-project/commit/974d649f8eaf3026ccb9d1b77bdec55da25366e5.

It’s an important fix to support CET correctly in LLVM. If it can’t catch up with LLVM10, it needs to fix in the next minor revision.
