Added helper function to automatically connect SPI slaves based on the QOM child
nodes of a device. A SSI master device can call this routine to automatically
hook-up all child nodes to its SPI bus.

Allow multiple qdev_init_gpio_in() calls for the one device. The first call will
define GPIOs 0-N-1, the next GPIOs N- ... . Allows different GPIOs to be handled
with different handlers. Needed when two levels of the QOM class heirachy both
define GPIO functionality, as a single GPIO handler with an index selecter is
not possible.

Added default CS behaviour for SSI slaves. SSI devices can set a property
to enable CS behaviour which will create a GPIO on the device which is the
CS. Tristating of the bus on SSI transfers is implemented.

Removed assertion that only one device is attached to the SSI bus.
When multiple devices are attached, all slaves have their transfer function
called for transfers. Each device is responsible for knowing whether or not its
CS is active, and if not returning 0. The returned data is the logical or of
all responses from the (mulitple) devices.

Commit 1d31fca470648ec66afd8743491bfb5846306341 tried to fix bug
introduced by 610b823ef66b993660f1ab1447a769f190e4f3b3 by including
qemu-common.h, which breaks the build further.
Include compiler.h instead, as suggested by Blue Swirl.

There are 6 temporaries that disas_sparc_insn relies on having been
allocated. Now that they are no longer referenced across branches,
they need not be allocated as local temps.

they are local to the translation of a single insn.

Share more code between unconditional and conditional paths.
Move the computation of the trap number into the conditional BB;
avoid using temporaries that have gone out of scope (cpu_tmp32)
or rely on local temps (cpu_dst).
Fully fold the exception number when the trap number is %g0+imm.

The pointer entry 'temps' always refers to the array entry 'static_temps'.
Removing the pointer and renaming 'static_temps' to 'temps' reduces the
size of TCGContext (4 or 8 byte) and allows better code generation.

Commit 610b823ef66b993660f1ab1447a769f190e4f3b3 uses QEMU_GNUC_PREREQ
on i386 hosts.
That macro is defined in qemu-common.h which is not always included
before qemu-barrier.h, so compilation on i386 hosts was broken.
