Currently, LLVM_VERSION_SUFFIX is cleared on release branches, which 
happens before the first release candidate, and it remains cleared once 
the release happens. See commit 7051e794 for when this was done for the 
12.x branch. So llvm-12.0.0rc5.src/CMakeLists.txt contains:


And this remained the same in llvm-12.0.0.src/CMakeLists.txt.
