	PR fortran/35681
	* dependency.c (gfc_check_argument_var_dependency): Add
	elemental check flag. Issue a warning if we find a dependency
	but don't generate a temporary. Add the case of an elemental
	function call as actual argument to an elemental procedure.
	Add the case of an operator expression as actual argument
	to an elemental procedure.
	(gfc_check_argument_dependency): Add elemental check flag.
	Update calls to gfc_check_argument_var_dependency.
	(gfc_check_fncall_dependency): Add elemental check flag.
	Update call to gfc_check_argument_dependency.
	* trans-stmt.c (gfc_trans_call): Make call to
	gfc_conv_elemental_dependency unconditional, but with a flag
	whether we should check dependencies between variables.
	(gfc_conv_elemental_dependency): Add elemental check flag.
	Update call to gfc_check_fncall_dependency.
	* trans-expr.c (gfc_trans_arrayfunc_assign): Update call to
	gfc_check_fncall_dependency.
	* resolve.c (find_noncopying_intrinsics): Update call to
	gfc_check_fncall_dependency.
