Prevent extraneous errors from returnjump_p with rtl checking

[Nick Clifton]

Hi Guys,

  The patch below prevents errors from being reported when RTL
  checking is enabled and returnjump_p() encounters insns which are
  not code insns.

  Is it OK to apply this patch ?

Cheers
	Nick

	* jump.c (returnjump_p): Do not examine insn which do not have
	a pattern (if RTL checking is enabled).
