Prevent extraneous errors from returnjump_p with rtl checking

[Nick Clifton]

Hi Richard,
  
: No.  It's either always wrong or it isn't.
: 
: Where's this getting called on non-jump_insn rtxs?


Oh poo!  You are right.  It was coming from my code to check to see a
return insn was being emitted with emit_insn rather than emit_jump_insn.
*sigh*  Please ignore my previous patch and tell me if the following
is better.

Cheers
	Nick

	* emit-rtl.c (emit_insn): Only check machine class insns for
	improper emission of a RETURN.
