Speed up dict_hash
This speeds up dict_hash a bit, by moving the "TKB" check into the switch in the loop. For "gdb -nx -readnow -batch gdb", this improves the time from ~9.8s before to ~8.5s afterward. gdb/ChangeLog 2017-11-09 Tom Tromey <tom@tromey.com> * dictionary.c (dict_hash): Move "TKB" check into the "switch".
