-	PR target/65689
-	* genpreds.c (struct constraint_data): Add maybe_allows_reg and

-	(maybe_allows_none_start, maybe_allows_none_end,
-	maybe_allows_reg_start, maybe_allows_reg_end, maybe_allows_mem_start,

-	(compute_maybe_allows): New function.
-	(add_constraint): Use it to initialize maybe_allows_reg and
-	maybe_allows_mem fields.
-	(choose_enum_order): Sort the non-is_register/is_const_int/is_memory/
-	is_address constraints such that those that allow neither mem nor
-	reg come first, then those that only allow reg but not mem, then
-	those that only allow mem but not reg, then the rest.
-	(write_allows_reg_mem_function): New function.
-	(write_tm_preds_h): Call it.
-	* stmt.c (parse_output_constraint, parse_input_constraint): Use
-	the generated insn_extra_constraint_allows_reg_mem function
-	instead of always setting *allows_reg = true; *allows_mem = true;
-	for unknown extra constraints.
-
-	* gcc.target/aarch64/c-output-template-4.c: New test.
