This fixes the himenobmtxpa miscompilation on ARM.

The PostRA scheduler got confused by the double memoperand and hoisted a stack

transitioning to a new refactored x86 SIMD specification.

 - Currently initialization is a bit of a hack, but harmless. We need to rework
   various parts of target initialization to clean this up.
