Now that we're always sparcv9, we can not bother using Bicc for
32-bit branches and BPcc for 64-bit branches and instead always
use BPcc.
New interfaces allow less direct use of tcg_out32 and raw numbers
inside the qemu_ld/st routines.

Avoid speculatively computing flags before every potentially trapping
operation and instead do the flags computation when a trap actually
occurs. This gives approximately 30% speedup in emulation.

The 'struct tm now' field in the state structure is in fact only
ever used as a temporary (the actual RTC state is held in 'offset').
Remove it from the state structure in favour of using local variables
to avoid confusion about whether it needs to be saved on migration.

The DS1338 datasheet documents that the current time is captured into
the secondary registers when the register pointer wraps round to zero
as well as at a START condition. Implement this.

Correct several deficiencies in the handling of the register pointer:
* it should wrap around after 0x3f, not 0xff
* guard against the caller handing us an out of range pointer
(on h/w this can never happen, because only a 7 bit value is
transferred over the I2C bus)
* there was confusion over whether nvram[] holds only the 56 bytes
of guest-accessible NVRAM, or also the secondary registers
which hold the value of the clock captured at the start of a
multibyte read. Correct to consistently be the latter, by fixing
the array size and the offset used for NVRAM writes.
* ds1338_send was attempting to use 'data' as both the data and
the register offset simultaneously, which meant that writes to
any register were broken; fix to use the register pointer.

A missing call to qemu_set_irq() when reading the IRQ register
required SW to write to the IRQ register to acknowledge an
interrupt. With this patch the behavior is fixed:
- Reading the interrupt register clears it and updates the timers
interrupt status
- Writes to the interrupt register are ignored

Because however the host, family, service and auth fields are

According to the spec we must raise an interrupt when one is requested
even for non active tds.
Linux depends on this, for bulk transfers it runs an inactivity timer
to work around a bug in early uhci revisions, when we take longer then
200 ms to process a packet, this timer goes of, and as part of the
handling Linux then unlinks the qh, and relinks it after the frindex
has increased by atleast 1, the problem is Linux only checks for the
frindex increases on an interrupt, and we don't send that, causing
the qh to go inactive for more then 32 frames, at which point we
consider the packet cancelled.
