Change Details

In all cases we now just set a single lib dir, so the somewhat newer `LLVM_LIBRARY_DIR` variable is more appropriate. I still defined `LLVM_LIBRARY_DIRS` for sake of downstream projects, but added a comment saying it was deprecated and should be removed. Is that correct? Also, I rearranged the definitions so they were more consistent.

There is a FIXME to add other directories to `LLVM_LIBRARY_DIRS`. If we don't do that, however, it is the same as `LLVM_LIBRARY_DIR`. This is sort of a "plan B" revision in case we don't do that FIXME. I still defined `LLVM_LIBRARY_DIRS` for sake of downstream projects, but added a comment saying it was deprecated and should be removed. Is that correct?
