A clean install or Cygwin functioned. I had to do a clean install because Cygwin failed after updating. I seem to have used the experimental version of mingw64 on Cygwin which did not agree with compiling intrinsics.
I suspect this newer version may also be in the opensuse mingw that msys2 uses. Not sure which thing exactly is causing the issue but it is telling that both failed at the exact same spot and using Cygwin's older versions (Cur not Exp) of the tools pass that spot perfectly fine. I am very confused with msys2 and llvm-svn. Somehow it believes it must use MSVC to compile LLVM.
