?  They all look like they can be fixed in the port.

Why not use :P?  From i386:

;; This mode iterator allows :P to be used for patterns that operate on                                                   
;; pointer-sized quantities.  Exactly one of the two alternatives will match.                                             
(define_mode_iterator P [(SI "Pmode == SImode") (DI "Pmode == DImode")])

(define_insn "*tls_global_dynamic_64_<mode>"
  [(set (match_operand:P 0 "register_operand" "=a")
        (call:P
         (mem:QI (match_operand 2 "constant_call_address_operand" "Bz"))
         (match_operand 3)))
   (unspec:P [(match_operand 1 "tls_symbolic_operand")]
             UNSPEC_TLS_GD)]
  “TARGET_64BIT"
