target-i386: fix crash on x86 32bit linux host with hw breakpoint exceptions

If you make use of hw breakpoints on a 32bit x86 linux host, qemu
will segmentation fault when processing the exception.

The problem is that the value of env is stored in $ebp in the op_helper...

These are unused since edea5f0 (no need to define global registers in
cpu-exec.c, 2008-05-10).

Handle init/sipi in a main cpu exec loop. (v2)

This should fix compilation problem in case of CONFIG_USER_ONLY.

Currently INIT/SIPI is handled in the context of CPU that sends IPI.
This patch changes this to handle them like all other events in a main
cpu exec loop. When KVM will gain thread per vcpu capability it will...

Add noreturn function attribute

Introduce noreturn attribute and attach it to cpu_loop_exit as well as
interrupt/exception helpers for i386. This avoids a bunch of gcc4
warnings.

[ Note that this patch comes with a workaround to include qemu-common.h
even in cases where is currently causes conflicts with dyngen-exec.h....

x86 cleanup

Remove some unnecessary includes, add needed includes, move prototypes to
cpu.h to suppress missing prototype warnings.

Remove unused functions and prototypes (cpu_x86_flush_tlb, cpu_lock,
cpu_unlock, restore_native_fp_state, save_native_fp_state)....

Common cpu_loop_exit prototype

All archs use the same cpu_loop_exit, so move the prototype in a common
header. i386 was carrying a __hidden attribute, but that was empty for
this arch anyway.
