Debug message updates:

- Shrink messaging during resets, primarily by getting rid of
   "nothing happened" noise that hides *useful* information.

 - Improve: the "no IDCODE" message by identifying which tap only
   supports BYPASS; and the TAP event strings.

Related minor code updates:

 - Remove two needless tests when examining the chain:  we know
   we have a TAP, and that all TAPs have names.

 - Clean up two loops, turning "while"s into "for"s which better
   show what's actually being done.
