[Patch, fortran] Avoid creating unnecessary type node

Hi,

another obvious patch that I intend to commit in 24h, unless objections 
arise. We don't need to create tree gfc_index_int_type_node, which is 
identical to tree gfc_array_index_type.

	* trans-decl.c (gfc_build_builtin_function_decls): Use existing
	gfc_array_index_type rather than creating another typenode for
	gfc_index_integer_kind.
