	PR fortran/46331
	* intrinsic.c: Correctly set the pure attributes for intrinsic
	functions.
	* expr.c (check_specification_function): Remove this function and move
	its code into gfc_is_constant_expr. (gfc_is_constant_expr): Change the
	order of checks by checking for non-constant arguments first.  Then,
	check for initialization functions, followed by intrinsics.
