@arsenm I can consolidate these enums but I would like to be sure that I am allowed to do it. I was not sure why Clang enum has smaller range in comparison to LLVM enum.
My initial aim of this patch was to perform minimal code refactoring so that Clang and Flang can reuse the same enum. If you wish I can consolidate Flang, Clang and LLVM enums.
