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.
