Fix conditionals on obsolete --threads 0

Browse Source 
Since we removed --threads 0 support, the 'threads()' option always
returns a value >= 1. Remove corresponding dead code.

Some of the coverage counters appear to use atomics even if the model is
single threaded. I'm under the impression this was a bug originally so
those ones I changed to use threads() > 1 instead.
