Hi,

Whilst working on the Reproducible Builds effort [0] we noticed that
python-peachpy could not be built reproducibly.

This is because it was iterating over data structures in a
nondeterministic manner resulting in non-normative differences such
as:

  -<li><p>VEXPANDPD(ymm{k}{z}, ymm/m256)    [AVX512F and AVX512VL]</p></li>
   <li><p>VEXPANDPD(xmm{k}{z}, xmm/m128)    [AVX512VL]</p></li>
  +<li><p>VEXPANDPD(ymm{k}{z}, ymm/m256)    [AVX512F and AVX512VL]</p></li>

and:

  -        self._implicit_out_regs = {0: 7, 2: 7}
  +        self._implicit_out_regs = {2: 7, 0: 7}

Patch attached.
