Removed the explicit SSI mux and wired the CS line directly up to the SSI
devices.

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.

Slave creation function that can be used to create an SSI slave without
qdev_init() being called. This give machine models a chance to set properties.

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.

qemu-barrier: Fix compilation on i386 hosts
|
|
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.

Aka "normal" comparisons. We now have the infrastructure to
pass back non-boolean results from gen_compare. This will
automatically get used by both branches and conditional moves.

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.
Move the allocation/free of these temporaries to make it clear that
they are local to the translation of a single insn.

The branches around the exception are maintaining an otherwise
unnecessary use of local temps for the cpu destination.
Note that gen_op_t{add,sub}_cc were identical to gen_op_{add,sub}_cc.

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.
