To answer a question that was put to me off-list, the code in question
is virtually identical to that generated by the i386 tcg_out_qemu_ld()
and tcg_out_qemu_st() functions[1], with the exception that the TCG
functions also handle loads/stores that are 64-bit and/or big-endian.

[1] Assuming that tcg_out_qemu_ld() and tcg_out_qemu_st() are commented
correctly -- I didn't actually check the generated machine code, but
I've no particular reason to distrust it.
