Chris Lattner 23a0199f05 now that addc/adde are gone, "ADDC" in the X86 backend uses EFLAGS results, 
the same as setcc.  Optimize ADDC(0,0,FLAGS) -> SET_CARRY(FLAGS).  This is
a step towards finishing off PR5443.  In the testcase in that bug we now  get:

	movq	%rdi, %rax
	addq	%rsi, %rax
	sbbq	%rcx, %rcx
	testb	$1, %cl
	setne	%dl
	ret

instead of:

	movq	%rdi, %rax
	addq	%rsi, %rax
	movl	$0, %ecx
	adcq	$0, %rcx
	testq	%rcx, %rcx
	setne	%dl
	ret
