clear `stack_end`.
* cont.c (cont_save_thread): clear only `stack_end`. Clearing tells GC mark function to ignore this macine stack (not allocated yet). `stack_start` will be used by machine stack store/restore phase (on FIBER_USE_NATIVE == 0), so that only `stack_end` is cleared. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59829 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
