tokhash: Speed up the rejection of unhashed values

Speed up the rejection of unhashed values (typically identifiers) by
filling unused hash slots with a large value (but not so large that
it is likely to overflow.)  This means those values will be rejected
already by the range check, not needing strcmp().
