3fb2968f2f make the vector conversion magic handle multiple results. 
We now compile test2/test3 to:

_test2:
	## InlineAsm Start
	set %xmm0, %xmm1
	## InlineAsm End
	addps	%xmm1, %xmm0
	ret
_test3:
	## InlineAsm Start
	set %xmm0, %xmm1
	## InlineAsm End
	paddd	%xmm1, %xmm0
	ret

as expected.

41f6259a4b add support for multiple return values in inline asm. This is a step 
towards PR2094.  It now compiles the attached .ll file to:

_sad16_sse2:
	movslq	%ecx, %rax
	## InlineAsm Start
	%ecx %rdx %rax %rax %r8d %rdx %rsi
	## InlineAsm End
	## InlineAsm Start
	set %eax
	## InlineAsm End
	ret

which is pretty decent for a 3 output, 4 input asm.
