New Issue: Make CHPL_LLVM=system independent of the third-party/llvm directory

16326, “bradcray”, “Make CHPL_LLVM=system independent of the third-party/llvm directory”, “2020-09-02T22:22:39Z”

As I understand it, at present, when CHPL_LLVM=system, we store some generated files in third-party/llvm. Organizationally speaking, this seems odd/surprising to me as I’d expect everything in third-party/llvm to only relate to the bundled CHPL_LLVM=llvm configuration. This issue asks whether such files could be moved to the build/ directory or elsewhere.
