{Enumerable,Array,Range}#first, {Array,Range}#last with blockfeature/enumerable-first-with-block
* array.c (rb_ary_first, ary_last): extend Array#{first,last} to accept
a block. If a block is passed, these methods collects only elements
for which the block returns a truthy value.
* enum.c: extend Enumerable#first to accept a block.
* range.c: extend Range#{first,last} to accept a block.
* gc.c: avoid using rb_ary_last(), because it may call a block.
* test/ruby/test_array.rb: add test
* test/ruby/test_enum.rb: ditto
* test/ruby/test_range.rb: ditto
