Block-receiving Range#count should always use Enumerable logic. Also add single-arg form which falls back on Enumerable. Fixes jruby#8955
These specs are lightly-modified versions of the same specs from Enumerable#count, but those specs depend on the Enumerable having multiple of the same value. A shared spec could probably be pulled out. See jruby#8955.

Logic installed to prevent large ranges from manually iterating to calculate a count (79ee920) short-circuited the fallback on
Enumerable#countlogic. That brokecountwhen passed a block (as described in #8955). Additionally, we did not handle the case whereRange#countis passed an argument.This PR fixes both cases and adds specs.
