    Update qemu_cfg_read to use "rep insb".

Use rep insb instead of manual loop - the host may be able to optimize
    the rep insb instruction.

Which doesn't make any sense - will do more testing.


Confirmed with multiple tests.


I think it's a miscompile.

out/code16.o:
 1a4:   3e                      ds
 1a5:   6c                      insb   (%dx),%es:(%edi)

Note no 66 prefix.
