In case of horizontal polarization entitlement has no effect on
ordering.
Moreover, since the comparison is used to insert CPUs at the correct
position in the TLE list, this affects the creation of TLEs and now
correctly collapses horizontally polarized CPUs into one TLE.

LAALG uses op_laa() and wout_addu64(). The latter expects cc_src to be
set, but the former does not do it. This can lead to assertion failures
if something sets cc_src to neither 0 nor 1 before.
Fix by introducing op_laa_addu64(), which sets cc_src, and using it for
LAALG.

Unfortunately, standard Mac keyboards do not include a "Right-Ctrl" key,

Before commit "hw/ide: reset: cancel async DMA operation before
resetting state", this test would fail, because a reset with a
pending write operation would lead to an unsolicited write to the
first sector of the disk.
The test writes a pattern to the beginning of the disk and verifies
that it is still intact after a reset with a pending operation. It
also checks that the pending operation actually completes correctly.

If there is a pending DMA operation during ide_bus_reset(), the fact
that the IDEState is already reset before the operation is canceled
can be problematic. In particular, ide_dma_cb() might be called and
then use the reset IDEState which contains the signature after the
reset. When used to construct the IO operation this leads to
ide_get_sector() returning 0 and nsector being 1. This is particularly
bad, because a write command will thus destroy the first sector which
often contains a partition table or similar.
