The repro code to crash clang

I think the summary says it all. When you have two enums, with the second
settings its member values to be bitwise ORing of the first's values clang
crashes on compile.  Simplified repro attached. It doesn't appear to want to
allow me to attach multiple items, or I can't figure out how. So the .sh file
produced is just this:
