  • movlhps and movhlps instructions only work with registers. To support operands
    in memory, need to generate movhps and movlps. They have the same opcodes, but
    different assertions in SBCL's assembler.
  • Modify def-binary-intrinsic to accept a keyword parameter :mem-alt-insn to
    specify the instruction to use if the src operand is in memory.
