I see the problem:

define_insn_and_split "*fixuns_trunc<mode>_1" is a post-reload splitter that
calls  ix86_split_convert_uns_si_sse after reload. There we have:

 gen_sse2_loadlpd (value, CONST0_RTX (V2DFmode), input)

and this calls sse2_loadlpd expander that wants to fixup its operands by
forcing something in a register.

Posted patch will fix the failure.
