(Preface: rr-dataflow is awesome 馃憤 )

Seems to have trouble parsing this code:

movdqu 0x10(%ebx,%eax,1),%xmm1

Which I get this from:

0xf7b7bdcb in ?? () from /lib32/libc.so.6
>>> origin
0x1000:	movdqu	xmm1, xmmword ptr [rbx + rax + 0x10]
not move movdqu
3
Traceback (most recent call last):
  File "~/rr-dataflow/flow.py", line 162, in invoke
  File "~/rr-dataflow/flow.py", line 105, in eval_mem_operand
NameError: name 'src' is not defined
Error occurred in Python command: name 'src' is not defined
>>> 

Could be worth noting this is a 32-bit binary, built on Ubuntu 17.10

I'll take a look. It shouldn't be too hard to fix.

I pushed a local change that I had forgot to push upstream. It might fix it.

Also, I don't think I've tried using it on 32-bit binaries so watch out for bad results.
