patch 8.0.0190: finding duplicate tags uses a slow linear search

patch 8.0.0190: finding duplicate tags uses a slow linear search
Problem: Detecting duplicate tags uses a slow linear search.
Solution: Use a much faster hash table solution. (James McCoy, closes https://github.com/vim/vim/issues/1046)
But don't add hi_keylen, it makes hash tables 50% bigger.
