refactor torexp to use routine in array.c

Browse source 
Found a part where copy&paste can be eliminated.  Reduces vm_exec_core
from 26,228 bytes to 26,176 bytes in size on my machine. I believe it
does not affect any runtime performance.

----

	* array.c (rb_ary_tmp_new_from_values): extend existing
          rb_ary_new_from_values function so that it can take
          additional value for klass.
	* array.c (rb_ary_new_from_values): use the new function.
	* insns.def (toregexp): ditto.
