C++: cpp/incomplete-parity-check: medium precision

Browse Source 
As reported in CPP-236, this query has false positives on signed
integers that cannot be negative. It could possibly be improved with a
local range analysis, but the query would most likely still have so many
false positives that we would have to lower its precision.

Under our current policy, this change will make the query hidden by
default on LGTM.
