Enumerable#all?, #any?, #one?, and #none? do not use yielded arguments as an Array. So they can use rb_block_call2 to omit array allocatoin.
Enumerable#find does not have to immediately accept yielded arguments as an Array. It can delay array allocation until the predicate block returns truthy.
(TODO: Enumerable#count and #find_all seem to be optimizable as well.)

Use rb_block_call2 for some Enumerable methods
